BGP counter graph has a lot of holes

Wunk · Post by **Wunk** » Tue Jun 20, 2006 7:32 am

Yesterday I installed a BGP counting template for cisco switches, but it seems to be generating a lot of holes..

The SNMP connection to the router itself is good, because there's no holes in the temperature or traffic graphs..

Anyone got a hint why this might be happening ?

Change the logging level to medium or high for a while and watch the bgp snmp data that is returned. Are there gaps in the data?

Does the BGP stuff use plain SNMP? Or perhaps a long running script, so changing the max runtime should be considered?

I would also check the CPU on the router, maybe it's to busy to respond.

Hi,

I was wondering if you could post your template and script?

Thanks[/code]

No, router is still not live in production so has 0 to 1% CPU load at all times..
I'll debug de SNMP logging tomorrow and keep it posted here (which should be fun, I'm polling well over 170 devices generating a few thousand graphs

)

And yeah, it's SNMP counters it polls from the router

Btw, it's this script:

If you're using cactid (I suppose so seeing this number of devices) debugging is much easier.
1) Get the ID of your host: Edit the host and remember the number seen in the url
2) run cactid --verbosity=5 <ID> <ID>, e.g. cactid --verbosity=5 42 42 assuming the host's id would be 42

Yeah, I'm using cactid

[root@stats cactid]# ./cactid --verbosity=5 261 261
ERROR: Cactid requires either 0 or 2 input parameters
USAGE: <cactidpath>/cactid [start_host_id end_host_id]

And with only 1 host argument:
[root@stats cactid]# ./cactid --verbosity=5 261
CACTID: Using cactid config file [cactid.conf]
CACTID: Version 0.8.6e starting
[root@stats cactid]#

that's it..

That is an older version of Cactid. What version of Cacti are you using?

Wunk · Post by **Wunk** » Wed Jun 21, 2006 9:12 am

0.8.6e, lemme upgrade that first..

Post by **rony** » Wed Jun 21, 2006 9:14 am

Please upgrade Cacti and Cactid.

Hi,

I am using latest versions of cacti and cactid (cacti-0.8.6h, cactid-0.8.6g), and having the same problem.

Any suggestions?

regards

After upgrading cactid the problem still existed, any output was fine in debugging mode though..

But after creating a graph for a new peer it was suddenly fine, so I deleted the existing BGP update graphs+datasources and recreated them and it's all ok now..

I'm thinking some kind of RRD corruption caused it..

Possible, um, this is interesting..

Can you email me the supposed corrupted rrd file?

I already removed and recreated the datasources and graphs, so I'm afraid I don't have them anymore..
