[Solved] SNMP Informant Memory Graphs broken in 0.87b?

[AndyStewart]

Since the upgrade to 0.87b, my SNMP Informant memory graphs seem to be blank.

Graphs are all fine up until the upgrade, and all other SNMP Informant graphs seem ok (disk usage, CPU, SQL Stats all fine)

Anyone else seen this?

Debug mode on the data sources all "seems" ok, can't spot any errors, but its just returning 0 data...

PS, as per http://forums.cacti.net/viewtopic.php?t ... ant+memory this link, i've changed the OID's for SNMP Informant STD.

These graphs have been working great for over a year, just after some pointers as to what I can check in 0.87b to resolve this issue - cheers.

Are the scripts returning data?
Are the rrd files getting updated with data?

[AndyStewart]

Found out what it was.

Prior to the update to 0.87b, the OID that was being checked for available and committed memory was .1.3.6.1.4.1.9600....etc

I removed the LEADING . from the OID and now it works.

[AndyStewart]

Ignore that previous entry - its still dead.

Running GetIf shows the data fine, the data source is a "Get SNMP Data", and the OID is set to ".1.3.6.1.4.1.9600.1.1.2.1.0"

Is there any way I can test that this is working correctly? such as check that the snmp.php script is working correctly?

[BSOD2600]

Sure. Change cacti's logging level to debug, let the poller run, then look either in the snmp cache or the cacti.log file for the output from the script.

Is the script a php script server script (i.e. ss_*) ? If so, then you can manually run it with the script server to test.

[AndyStewart]

ok Finally tracked it down.

The SNMP Informant memory graphs (and SNMP Informant TS Sessions graphs), all had a step of 60 under Data Templates - changed this to 300 to match the other data templates and the graphs started working again.
