BVQ V5.3.3 released Minor bugfix release
Performance analysis and monitoring for IBM SVC and Storwize



Name of the Solution:
Special Dashboards to download


These dashboards go deep into the performance analysis. They can only be used with a full licensed BVQ server because only this server is providing the in depths metrics which are used here.
Of course, the analysis dashboards do not have the interactivity and efficiency of a BVQ GUI, but they do allow some of the important analysis steps to be easily used. They maybe will help in day-to-day business when it comes to just gaining a picture of a situation without the need for a deep GUI analysis. These favorites are complex and constantly evolving. They are distributed on an as-is basis and are not officially maintained as part of the BVQ distribution.

The is an example of the host analysis dashboard which shows every volume of a host with io and latency.

The idea behind these dashboards is easy to understand step by step analysis

  • Step 1: Recognize the problem

A latency peak becomes visible- this is monitoring and recognizing - probably a BVQ alert has fired

  • Step 2: group the problem

Can this problem be grouped into a host, an storage pool or is it only a single VDisk problem
Analyze this group with the Analysis dashboard for host, for application, for managed disk group or for single VDisk

  • Step 3: find the cause of the problem

There are 4 deep checks assembled into this dashboard:

    1. is it a storage backend problem?
    2. is it a cache hit problem?
    3. is it a cache partition problem?

is it a server performance problem?

    1. is it a node port problem ?

Pict.: Deep analysis and quite easy to understand. This picture shows an example of the analysis dashboards which help to track down a problem into the single problem areas.
