CPU Graph Problem

Boulad · Post by **Boulad** » Tue Jun 24, 2008 1:55 pm

All my graphs which are the same template work fine except my CPU one. On some servers I get 0 as the value on the graph and on other servers I get NaN.

I already checked out gandalfs link to debugging... it still doesn't work. I would really appreciate some help because I've been struggling with this for a number of days now.

Fien that you've found my debug instructions. Now I need results of each step to get an idea what's failing. Step-by-step, please

Step 1 (Check Cacti Log File):

I'm receiving
"WARNING: Result from CMD not valid. Partial Result: "
in the Cacti Log.

I'm not receiving
"CACTID: Host[...] DS[....] WARNING: SNMP timeout detected [500 ms], ignoring host '........'"
anywhere.

Step 2 (Check Basic Data Gathering):

When I run the 'sudo su - root /usr/local/cacti/scripts/f5-bigip-tmm-cpu.pl
<hostname> <snmp community>' command the output is the following:

Code: Select all

/usr/local/cacti/scripts/f5-bigip-tmm-cpu.pl: line 6: syntax error near unexpected token `('
/usr/local/cacti/scripts/f5-bigip-tmm-cpu.pl: line 6: `use Net::SNMP qw(:snmp);'

I didn't think much of this because my TMM-memory scripts also brings up errors, but works just fine. This is the output I get if I run the TMM memory script if you are curious.

Code: Select all

/usr/local/cacti/scripts/ss_f5-bigip-tmm-memory.php: line 1: ?php: No such file or directory
/usr/local/cacti/scripts/ss_f5-bigip-tmm-memory.php: line 2: =: command not found
/usr/local/cacti/scripts/ss_f5-bigip-tmm-memory.php: line 4: /1: Permission denied
/usr/local/cacti/scripts/ss_f5-bigip-tmm-memory.php: line 5: syntax error near unexpected token `E_ERROR'
/usr/local/cacti/scripts/ss_f5-bigip-tmm-memory.php: line 5: `error_reporting(E_ERROR);'

For snmpget I'm putting in ' snmpget -c public -v 2c bigip1.xxx.xxx.com .1.3.6.1.4.1.2021.10.1.3'
and receiving the following:

Code: Select all

UCD-SNMP-MIB::laLoad = No Such Instance currently exists at this OID

but with 'snmpwalk -c public -v 2c bigip1.xxxx.xxx.com .1.3.6.1.4.1.2021.10.1.3'
I'm receiving:

Code: Select all

UCD-SNMP-MIB::laLoad.1 = STRING: 1.02
UCD-SNMP-MIB::laLoad.2 = STRING: 1.03
UCD-SNMP-MIB::laLoad.3 = STRING: 1.00

Step 3 Check cacti's poller:
Verified that my crontab is showing poller.php. I have cmd.php selected as my poller type.

I went ahead and changed Poller Logging Level to 'DEBUG'. Looking at the Cact.log I found this output.

Code: Select all

06/25/2008 10:20:22 AM - PHPSVR: Poller[0] DEBUG: PHP Script Server Shutdown request received, exiting

The path /usr/local/cacti/scripts/ is correct. The name of the file is correct too.

--------------------------------------------------

Not sure if you want me to keep on going gandalf or if you have already spotted the error. Please let me know. I've attached the TMM-cpu file that i'm using along w/ a pic of evidence that my TMM memory is working fine. (Reminder: I'm using ver 0.8.7a) One thing that I'd like to add, my memory_limit under PHP Information in the Cacti Technical Support is stating that "It is highly suggested that you alter you php.ini memory_limit to 16M or higher." I increased it to 32MB (I have yet to restart the web server for it to take effect, it is still currently reading 8MB), not sure if this would have anything to do with the problem.

Please edit the data input method. Replace "perl" by "/full/path/to/perl". Then run ./cli/rebuild_poller_cache.php and retry

I went to Data Input Methods and put in the following for Input String:
/usr/local/perl <path_cacti>/scripts/f5-bigip-tmm-cpu.pl <hostname> <snmp_community>

Then ran the Rebuild Poller Cache.

Code: Select all

Sadly, it is still not working.

I would like to add that I have other scripts that use perl and they work fine.

Example: Input String for a load balance script for the server that Cacti is running on:
perl <path_cacti>/scripts/loadavg_multi.pl

Bump. What should I do? Did I execute your suggestion incorrectly gandalf?

Boulad · Post by **Boulad** » Thu Jun 26, 2008 2:45 pm

Bump. Any help from anyone would be greatly appreciated. I've been working on this bugger for days now.

Friendly Bump

I'm not really sure on this, because you've claimed thta the other script works fine. But I really recommend debugging your script until errors are gone. You may post the script here (did I see it in another post?).

Here is the CPU script that I'm using. Just a friendly reminder, I'm using Cacti 0.8.7a. The data and graph I'm importing.

Any chance for an online debug session? If yes, please provide data via pm
