Problem with the consistency of the graphs in Cacti0.8.7b

[praveen_b744]

I am getting graphs with my Cacti0.8.7b. But those are inconsistence. i.e. there are breakup's in the graphs.

I had gone through the cacti.log and poller.log.

I suspect the following log in cacti.log

19/05/2008 09:59:01 AM - CRONJOB: Cacti database flush start
19/05/2008 09:59:01 AM - CRONJOB: Size of poller_output before truncate: 1
19/05/2008 09:59:01 AM - CRONJOB: Cacti database flush end
19/05/2008 11:05:01 AM - CRONJOB: /tmp/cacti.lock exists. Poller disabled.
19/05/2008 03:05:01 PM - CRONJOB: /tmp/cacti.lock exists. Poller disabled.
19/05/2008 10:35:02 PM - CRONJOB: /tmp/cacti.lock exists. Poller disabled.
19/05/2008 11:05:02 PM - CRONJOB: /tmp/cacti.lock exists. Poller disabled.
20/05/2008 01:05:01 AM - CRONJOB: /tmp/cacti.lock exists. Poller disabled.
20/05/2008 03:05:01 AM - CRONJOB: /tmp/cacti.lock exists. Poller disabled.
20/05/2008 09:59:01 AM - CRONJOB: Cacti database flush start


And I suspect the following log in poller.log,

OK u:0.30 s:0.72 r:155.75

And I find these breakups mainly in "CPU Utilization" graphs
Can any one plz suggest the cause for the inconsistency in my graphs?

[gandalf]

The last errors are related to an old script using cacti_snmp_get function (which is NOT a published API). With cacti 087, cacti_snmp_get received some more parameters to fully support SNMP V3.
So please check, if the script used is available in an updated version.

Thanks for the reply.

But we are using SNMP version2

I have gone through the Debug mode of few graphs which has gaps. And I feel it is fine.

The following is one of the output of the debug mode of the graph,

RRDTool Says:

OK

What will be the other probabilities for these type of issues?

Thanks for the reply.

But we are using SNMP version2

That does not matter. The function call now requires more parameters. They may be empty, but must exist.
