Hi,

recently we are having gaps in one of the SVC graps:



What could be the problem?

    Hi,

    Do you use latest 2.20 version? if not the upgrade at first.

    How many nodes it has? 8? if so then 10 minute sample interval switch will help.
    Just confirm it, I would let you know how to do it.

    Hi,

    yes, we are using the latest version. We have 6 Nodes in the cluster. If you think we still need to switch the interval, please let me know how to do it.

    Hi,

    Edit etc/storage-list.cfg (10 minutes parameter at the end)
    svc-alias:SWIZ:192.168.1.1:
    -->
    svc-alias:SWIZ:192.168.1.1::::10

    kill svcperf for svc-alias
    ps -ef| grep svcperf| grep svc-alias

    Let it work and let us know.

    Hi Pavel,

    I have applied the parameter, but I cannot see any change, we still have the gaps in the graph.

    assure it really work for 10 minutes.
    open tmp/<svc-alias>*perf*txt

    There is timeframe in the header of each section like:
            Interval Length:  300 seconds

    is there 600 seconds?

    It looks like this:

            Interval Start:   2018-02-28 10:37:31
            Interval End:     2018-02-28 10:42:31
            Interval Length:  300 seconds

    it still uses 5 minutes.

    grep <svc-alias> etc/storage-list.cfg
    ps -ef| grep <svc-alias>
    date

    Here is the output:

    grep stsvc10 etc/storage-list.cfg
    stsvc10:SWIZ:10.5.118.193:/home/zenoss/.ssh/id_dsa:::10

    ps -ef | grep stsvc10

    1. have you set it in storage-list.cfg today or yesterday?
    2. product version.

    1. yesterday
    2. Version 7.8.1.4 (build 135.5.1712071656000)

    weird, it should force it to 10 minutes, just tested it and it worked.
    try to kill it and check it out after 15 - 20 minutes.

    kill 11291    
    vi tmp/stsvc10-perf-last.txt

    there should be:
            Interval Length:  600 seconds

    Unfortunately no change:
     Interval Start:   2018-03-02 07:58:40
            Interval End:     2018-03-02 08:03:40
            Interval Length:  300 seconds

    Now it is a bit better, but we still have a gap between 22:50 and 23:30 every day.
