Hi Team,

Request your help on below issue.

We are getting the channel bandwidth graph showing as undefined (Old performance data) after removing the channels for ASI. Please find the attached screenshot.


Note: We could see that the rrd files are not getting updated but xml files are getting updated.

[root@nagios tvips-223]# ls -l ASI_3_MT-82_11641H__Channel_Bandwidth.rrd
-rw-rw-r-- 1 nagios nagios 1534768 Dec 22 12:36 ASI_3_MT-82_11641H__Channel_Bandwidth.rrd
[root@nagios tvips-223]# ls -l ASI_3_MT-82_11641H__Channel_Bandwidth.xml
-rw-rw-r-- 1 nagios nagios 3171 Dec 22 16:37 ASI_3_MT-82_11641H__Channel_Bandwidth.xml
[root@nagios tvips-223]#

Thanks,
Sanoj

If you ever change the quantity of of datasources a check returns, you need to delete the historical RRD file (ASI_3_MT-82_11641H__Channel_Bandwidth.rrd) and let it be recreated (yes you will lose the historical data)

This is because the RRD files have a pre-set amount of datasources from the time they are created and the data will not be able to update if this ever changes.
