No performance data saved if number of variables go down
Posted: Thu Aug 14, 2014 10:31 am
We have created a script that reads the IOPS per volume for our NetApp controllers.
The script returns the iops per volume as data and as performance data and has been working perfect for a couple of months eg :
Today we have seen that some of the services haven't been adding any data to the performance grahps since a couple of weeks.
The problem seems to occur on the controllers were we have deleted some volumes eg :
If we delete one of the volumes, the script returns data for the remaining volumes but the performance graphs fail.
It shows vol0, nfs_iit, nfs_temp & series 4 and does not save the performance data anymore until we add a 4th volume again.
Here's an example graph I'm pretty sure that the problem is not related to our script.
Has anyone seen this with any other service that has a variable number of results returned as performance data ?
