Discovering Virtual Platforms

By default, the eG manager attempts to discover virtual platforms using the port-scanning technique (that was described earlier in this chapter). In the case of some virtual platforms, this technique may not be effective. In case of a few others, security considerations may discourage administrators from opting for this technique. To address these concerns, eG Enterprise allows administrators the flexibility to discover virtual platforms without running the port scans. How this is done differs from one virtual platform to another. The sub-sections below elaborate on how each virtual platform can be discovered using the eG manager.

Discovering vSphere/ESX Servers

eG Enterprise is capable of automatically discovering the ESX servers in the environment using the eG manager or the eG agent that is monitoring the ESX server. Since both these approaches employ a port-scanning technique to discover ESX servers, they might not be suitable for high-security environments where the firewall has been configured to block traffic to and from specific ports. Likewise, in environments that are spread across multiple sub-nets, discovery performed using the eG manager or the agents could increase the bandwidth consumption. To address these concerns, eG Enterprise provides you with the option to directly connect to one/more VMware vCenter installations in your environment to perform ESX discovery. The additional benefit that accrues in this process is that, when one/more ESX servers discovered using vCenter are managed, then eG Enterprise automatically uses the same vCenter server to collect performance metrics related to the ESX servers. In other words, eG Enterprise auto-configures the tests pertaining to the managed ESX servers with the details of the vCenter server used for their discovery; this way, the solution minimizes the time and effort involved in manual test configuration, and quickly starts collecting metrics from vCenter. Similarly, if the vCenter details need to be modified for any reason, then, you will not be required to manually reconfigure each test for this purpose; changing the configuration of the vCenter server in the discovery page will automatically update all the tests that have been configured to collect metrics from that vCenter server.

To discover the vSphere/ESX hosts, select the Virtual Platforms option under the Settings sub-node of the Manager Discovery node in the discovery tree in the left panel of Figure 1. Then, choose the vSphere/ESX Hosts option from the Choose a virtual platform to discover drop-down in the right panel (see Figure 1). If one/more vCenter servers have already been added to enable the discovery of vSphere/ESX servers, the details of the same will be displayed in the right panel as shown by Figure 1.

Discovering vSphere/ESX Hosts

Figure 1 : Discovering vSphere/ESX Hosts

The first step towards using vCenter for ESX discovery and performance monitoring is to configure the eG manager with the details of the vCenter server(s), and mark the server(s) that will be used for discovery.

Prior to vCenter creation, you might have to increase the memory settings of the eG manager. This is because, VI APIs are memory intensive, and therefore, the default memory setting of 128 MB for the eG manager might not be sufficient for performing ESX discovery via vCenter. To override this default setting, select the Configure memory settings for discovery option from the What action would you like to perform? drop-down list in the right panel of Figure 1. Figure 2 will then appear.

Overriding eG Manager's Default Memory Settings

Figure 2 : Overriding the default memory settings of the eG manager

You can specify any value between 256 MB and 1024 MB in the Memory Range (MB) text box in Figure 2, and click the Update button therein.

Next, you can proceed to add a new vCenter. To add a new vCenter server, do the following:

  1. Select the Add new vCenter option from the What action would you like to perform? drop-down in the right panel (see Figure 3).

    Adding vCenter Server

    Figure 3 : Adding a vCenter configuration

  2. Then, specify the following in right panel of Figure 3:

    • Specify the IP or host name of the vCenter in the vCenter identity (IP or Host name)text box.

      Note:

      When providing the IP address of the vCenter server against vCenter identity, you can specify either the IPv4 or the IPv6 address of the vCenter server.

    • Then, indicate whether the eG manager is to connect to vCenter using SSL or not by selecting the Yes or No option from the Use SSL to connect to vCenter list. By default, this flag is set to Yes.
    • By default, in most virtualized environments, vCenter listens on port 80 (if not SSL-enabeld) or on port 443 (if SSL-enabled) only. This implies that while discovering ESX servers using vCenter, eG Enterprise communicates with vCenter via the default ports 80 or 443, depending upon the SSL-enabled status of vCenter.  Accordingly, the Web Port parameter in Figure 3 is set to 443 by default, if the ssl flag is set to Yes, and displays the default value 80 if the ssl flag is set to No. In some environments however, the default ports 80 or 443 might not apply. In such a case, in the Web Port text box, specify the exact port at which vCenter in your environment listens.
    • Typical virtualized environments may consist of multiple vCenter installations, each managing a different set of ESX servers. To enable the eG manager to automatically discover those ESX servers that are managed by the vCenter being added, then set the Discover ESX hosts using this vCenter flag to Yes. If not, then set it to No.
    • In order to be able to discover ESX servers using a vCenter server, the eG manager needs to connect to vCenter using the credentials of a valid user to vCenter. Provide the user name and password of such a user in the Username to connect to vCenter and Password for the user text boxes. This user typically requires Administrator or Virtual Machine Administrator privileges. However, if you cannot expose the credentials of such a user owing to security constraints, then, you can use the credentials of a user with ‘Read-only’ privileges to vCenter. If such a user pre-exists, then, provide the name and password of that user in the text boxes mentioned above. Otherwise, assign the ‘Read-only’ role to a local/domain user to vCenter, and provide the name and password of this user in the Username to connect to vCenter and Password for the user text boxes. The steps for achieving this are detailed in the Monitoring VMware Infrastructures document.
    • Confirm the password of the user by retyping it in the Confirm password for the user text box.
    • To clear all the configured details, click on the Clear button in Figure 3. To start discovery instead, click on the Update button.

    • Clicking on Update brings up Figure 4, which requests you to confirm whether you want to start discovery based on the specifications provided. Click the Yes button to begin discovery.

      Starting ESX Discovery

      Figure 4 : Starting ESX discovery

    • Regardless of the discovery approach used (discovery using an IP range or using vCenter), triggering ESX discovery will lead you straight to the components -manage / unmanage. To know how to manage/unmanage components using this page, refer to Managing and Unmanaging Components.

To view the vCenter servers so added, select the View configured vCenters option from the What action would you like to perform? drop-down. Figure 5 will then appear listing the vCenter servers that have been configured for discovering ESX servers.

Discovering IBM pSeries Servers

eG Enterprise is capable of monitoring the AIX LPARs that are operating on IBM pSeries servers using a patented 'In-N-Out' monitoring approach. The first step towards implementing this approach is to discover the IBM pSeries servers in the environment. To save administrators the trouble of manually adding each IBM pSeries server to be monitored, the eG management console facilitates the configuration of an HMC (Hardware Management Console) server, using which the IBM pSeries servers can be automatically discovered.

To discover the pSeries Servers using an HMC server, select the Virtual Platforms option under the Settings sub-node of the Manager Discovery node in the Discovery tree. Then, choose the pSeries Servers option from the Choose a virtual platform to discover drop-down in the right panel, as shown by Figure 10.

To add a new HMC server, do the following:

  1. Select the Add new HMC option from the What action would you like to perform? drop-down.

  2. In the right panel, specify the IP address of the Hardware management console to be used for the discovery.

    Note:

    Only an IPv4 address can be specified against IP address of the Hardware management console. 

    Adding HMC Server

    Figure 10 : Adding an HMC server

  3. Then, mention the Host Name of the Hardware management console.
  4. Next, indicate whether/not the eG manager needs to use SSL to connect to HMC. To use SSL, set the Use SSL to connect to HMC flag to Yes. Otherwise, set it to No.
  5. If more than one HMC server is deployed in your environment, you may want to discover the IBM pSeries servers using one of the HMC servers alone; you may still want to feed the eG manager with the details of the other HMC server, so that it can be used for discovery some time later. This is why, while configuring an HMC server using this page, you need to indicate whether/not the HMC server being configured is to be used for discovery or not. To use the HMC server for discovery, set the Discover pSeries servers using this HMC flag to Yes. Set the flag to No if you do not want to discover pSeries servers using this HMC server.
  6. Provide a valid user name for connecting to the HMC server in the Username to connect to HMC text box.
  7. Specify the Password for the user of the HMC user.
  8. Confirm the password by retyping it in the Confirm password for the user text box.
  9. Finally, click the Update button to save the changes.

  10. A message box will then appear requesting your confirmation to proceed with the discovery. Click the OK button to discover the pSeries servers, or click the Cancel button to cancel discovery.

Discovering RHEV Servers via the RHEV Manager

eG Enterprise embeds the ability to monitor the RHEV servers in an environment and the VMs operating on those servers. The first step to monitoring the RHEV servers is to identify those servers that require monitoring. The eG Enterprise system can auto-discover the RHEV servers in a virtualized environment using the RHEV managers that manage those servers. To enable this auto-discovery, you first need to enable the eG manager to connect to the RHEV manager in the environment. The Virtual Platforms sub-node in the discovery tree can be used for this purpose. This is how:

To discover the RHEV Servers, select the Virtual Platformsoption under the Settings sub-node of the Manager Discovery node in the discovery tree in the left panel of Figure 15. Then, choose the RHEV Hypervisors option from the Choose a virtual platform to discover drop-down in the right panel of Figure 15.

  1. First, you need to configure the RHEV manager with which the eG manager should connect for automatically discovering the RHEV servers that require monitoring. For this, select the Add new RHEV Manager option from the What action would you like to perform? drop-down.

    Adding RHEV Manager

    Figure 15 : Adding the RHEV Manager to be used for discovering the RHEV servers

  2. In the right panel of Figure 15, specify the following:

    • RHEV Manager identity: Specify the IP address/host name of the RHEV manager in your environment.

      Note:

      If you choose to specify the IP address of the RHEV manager against RHEV Manager Identity, then make sure that you specify only an IPv4 address.

    • Use SSL to connect to the RHEV Manager: Set this flag to Yes if the RHEV manager in your environment is SSL-enabled. Otherwise, set this flag to No.
    • Web Port: If the RHEV manager is SSL-enabled, then 8443 will be displayed here by default. On the other hand, if the manager is not SSL-enabled, the default Web Port will be 8080. If the RHEV manager in your environment listens on a different SSL or non-SSL port, then make corresponding changes to the default setting.
    • Discover RHEV Hypervisors using this RHEV Manager: If you want to discover RHEV servers in your environment using this RHEV manager, set this flag to Yes. If you only want to use this RHEV manager to obtain the outside view of VMs, set this flag to No.
    • Username to connect to RHEV Manager and Password for the user: Specify the credentials (i.e., user name and password) of a user who has been assigned the RHEVMUser role. If no such user pre-exists, then create a special user for this purpose, assign the RHEVMUser role to this user, and provide his/her login credentials here.
    • Confirm password for user: Confirm the password of the RHEVMUser by retyping it here.
    • Domain name for the RHEV Manager: Specify the name of the domain to which the RHEV manager belongs.

  3. Then, click the Update button in Figure 15. A message box requesting your confirmation to proceed with the discovery will then appear (see Figure 16. Click the ok button in the message to trigger the discovery. Clicking the Cancel button will save the details of the RHEV manager, but will not start the discovery. In this case, you can use the RHEV manager configuration so saved to perform discovery at a later point in time.

Discovering Citrix XenServers in a Citrix XenServer Pool

eG Enterprise embeds the ability to monitor the Citrix XenServers and the VMs operating on those servers. The first step to monitoring the Citrix XenServers is to identify those servers that require monitoring. The eG Enterprise system can auto-discover the Citrix XenServers in a itrix XenServer pool using the IP address of the Citrix XenServer within the pool. To enable this auto-discovery, you first need to enable the eG manager to connect to a Citrix XenServer in the Citrix XenServer pool. The Virtual Platforms sub-node in the discovery tree can be used for this purpose. This is how:

To discover the Citrix XenServers in a Citrix XenServer pool, select the Virtual Platforms option under the Settings sub-node of the Manager Discovery node in the discovery tree in the left panel of Figure 20. Then, choose the Citrix XenServers option from the Choose a virtual platform to discover drop-down in the right panel of Figure 20.

  2. In the right panel of Figure 20, specify the following:

    • Citrix XenServer identity (IP or Host name): Specify the IP address/host name of any server in a XenServer pool. eG Enterprise can connect to a member server or the master server in a pool for discovery. If the IP/host name of a master server is provided here, then eG Enterprise discovers the details of other servers in the pool directly from the master. On the other hand, if the IP/host name of a member server is specified, then eG Enterprise connects to that member server to figure out which is the master server in the pool. Once the master server is identified, eG Enterprise connects to the master to discover the details of the other XenServers in the pool.
    • Use SSL to connect to the Citrix XenServer: Set this flag to Yes if the Citrix XenServer in the pool is SSL-enabled. Otherwise, set this flag to No.
    • Web Port: If the Citrix XenServer is SSL-enabled, then 443 will be displayed here by default. On the other hand, if the Citrix XenServer is not SSL-enabled, the default Web Port will be 80. If the Citrix XenServer in the pool listens on a different SSL or non-SSL port, then make corresponding changes to the default setting.
    • Discover Citrix XenServers: If you want to discover the Citrix XenServers in a pool using this Citrix XenServer, set this flag to Yes. If you only want to use this Citrix XenServer to obtain the outside view of VMs, set this flag to No.
    • Username to connect to Citrix XenServer and Password for user: Specify the credentials (i.e., user name and password) of a user who has been assigned the pool-admin privilege or Read-only privilege. If no such user pre-exists, then create a special user for this purpose, assign the required privileges to this user, and provide his/her login credentials here.
