Monitoring SIOS DataKeeper

eG Enterprise offers a dedicated monitoring model for the SIOS DataKeeper cluster (see Figure 1).

Figure 1 : The layer model of a SIOS DataKeeper

Using the metrics reported by eG Enterprise, administrators can find quick answers to the following questions:

• What is the current status of the mirror?
• What is the type of mirroring each volume involved in?
• What is the current resynchronization phase of the volume?
• What is the time taken for resynchronizing the volumes?
• How many writes on the source volume to be resynchronized to the target volume?
• How many blocks are marked as dirty in the intent log while resynchronizing the volumes?
• How many network reconnects have been made while mirroring each volume?
• What is the current status of the job?
• What is the type of mirroring each job performed?
• What is the amount of space allocated for each job on the SIOS DataKeeper?
• How many days are left for the SIOS licenses to expire?

Since the five layers at the bottom of the SIOS DataKeeper monitoring model have been discussed in the Monitoring Unix and Windows Servers document, the section that follow will deal with the SIOS Service layer alone.
