got this error in log and graphs have "holes"

[rschitz]

This will be fix in the next update, could you try this one and let me know https://github.com/sexibytes/sexigraf/blob/dev/root/ViPullStatistics.pl

[kamilnew]

tried it but it doesnt work - got this in log file

[rschitz]

try the last version

[kamilnew]

now i got this errors in log:

virtual machines stats are working now
datastores latency and iops dont work at all

[rschitz]

is this one better? https://github.com/sexibytes/sexigraf/blob/069be584ff973b73d093fd5a8dacf1176185de4d/root/ViPullStatistics.pl

[kamilnew]

now there are no errors in logs but still no datastore data - i think there are datapoints but they are null

[kamilnew]

can you show me how manually gather information about datastores to check if this values are null because of problem in my environment?

btw. i wish my enterprise products have this quality of support :)

[rschitz]

Thanks for your support.
when you said "no datastore data" you talk about local datastores or shared one ? did you ever get data for those?

[kamilnew]

shared one`s - those from lower screenshot - they were partialy working when i was taking screenshot on older versoin of ViPullStatistics.pl yesterday
i check historic data on sexigraf and i lost iops data at 27th of september , at the same time "holes" in datastore latency appear - this was during vsphere/vsan reconfiguration and that is why i think it may be problem in my environment - try to find anything in logs

[rschitz]

holes generally means slow vcenter or too something that takes more than 5min to complete, by sliding pointer on the graphs you should see points but not enough to have lines.
check the Pull Exec Time dashboard to confirm

[kamilnew]

pull exec look ok - ill try to pull data manually to see what is misiing - im sure that is problem with my environemt - about 40% of datastores have data and 60% dont - thanks for help

[kamilnew]

problem solved - i disabled storage i/o control on several datastores and thats why there was no data

[rschitz]

we added "legacy" metrics for the datastores, you should had metrics anyway.

[rschitz]

the metric we try first is sizeNormalizedDatastoreLatency which is enable by default now but few version back you had to enable it manually: http://frankdenneman.nl/2013/02/11/how-to-enable-sioc-stats-only-mode/

[kamilnew]

yes it is enabled by default but i disabled it on purpose month ago - don`t even remember why :) thanks for help

[rschitz]

you're welcome, thanks for you support and feedback!
