Gaps in SVC Graphs

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:

    CPU-Node Level Statistics
            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
    zenoss   11291     1 60 00:00 ?        07:52:51 /usr/bin/perl -w /opt/serviced/volumes/stor2rrd/bin/svcperf.pl stsvc10
    zenoss   32404 26292  0 12:59 pts/0    00:00:00 grep --color=auto 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.
  • send us
    tail logs/error.log-<storage name>
    tail logs/output.log-<storage name>
