(Resolved )Custom Data query graph works in realtime view but not regular poller

[bmfmancini]

Hey Guys

I made a simple data source to graph optical levels
here is my query

It's been a while since I've run into this issue I usually have good luck creating my custom graphs and queries this one is being a bit difficult

Here is the setup

just 2 queries on for the sfp to find out if its internally or externally calibrated
and the OID for the light levels

<interface>
<oid_index>.1.3.6.1.4.1.6527.3.1.2.2.4.31.1.40</oid_index>
<index_order>calb:OptiPort</index_order>
<fields>



<calb>
<name>Calibration type</name>
<method>walk</method>
<output_format>value</output_format>
<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.4.1.6527.3.1.2.2.4.31.1.40</oid>
</calb>
<OptiPort>
<name>Optical Port Selection</name>
<method>walk</method>
<output_format>value</output_format>
<source>value</source>
<direction>input-output</direction>
<oid>.enterprises.6527.3.1.2.2.4.31.1.21.1</oid>
</OptiPort>
</fields>
</interface>


The graphs create wihtout issues but all NAN unless in realtime view where it works fine

doing a debug on the data source shows Last U and Value NaN
Permission are fine

I have the data query set to get SNMP indexed pointing to the graph template as a data source
so what is realtime doing differnt than the poller that it can get the graph working but the poller cant ?

Thanks guys !

[bmfmancini]

Any ideas on this anyone ???

[netniV]

More than likely a permission issue with the RRD directory.

[bmfmancini]

Permissions are fine

It's just this query and template that I'm having a problem with

I wish it was always something easy like permissions lol

[netniV]

It still sounds like permissions to me. The only real difference between the two is that Realtime doesn't go via the RRD's. And the poller often uses a different user to the http daemon.

[bmfmancini]

In my setup the killer is using the apache user
But let me triple Check

[bmfmancini]

wow for the typo lol killer = poller

I checked graph permissions they are good the DS comes back with NaN so not getting any values

the graph template works fine as well since realtime generated the graph
head-scratcher on this one

Here is the output of the query

Ok so I adjusted my query it now looks like this

this is to include the interface index as well
now the DS is reporting last value of 0 as of the last poll which is a good sign
lets see what happens

[bmfmancini]

well that was short lived
the data source now reports NaN again

[bmfmancini]

Oh here is the graph debug output as well

RRDtool Says:

OK

[netniV]

When editing the data source, does your RRD match the expected list of sources?

[bmfmancini]

sorry not following

the query is exporting the OptiPort field to the grah template

oh and just for refernce here is the RRA file permissions

What user does your poller run as from cron?
