[ferrero_sergio]

Already achieve that it was working for the machines Solaris, the problem was in the version of the snmp, because hize the proof of sending the script with the version 1 the snmp and it does not work but with the version 2 perfectly, without nothing problem, this way that I put snmp2 and already it(he,she) was doing(painting).
Thank you very much for everything

I just manage to log in to this forum. Being busy lately.

I will take a look on the script again.

Currently the quick modification may not work with SNMP v3 I think.

Hi Guys,

I was having problems as well with this script and modified source around line 163 like this:

$snmp_community,
$oid[$cmdoutputcount][1],
$snmp_version,
$snmp_username,
$snmp_password,
"MD5",
"",
"[None]",
"",
$snmp_port,
$snmp_timeout);


Hope this helps.

Hi,

i try to export the php script into snmp query xml, but if i change direction to input in the xml script, there's no drop down menu in the Associated Graph Templates, with direction output the drop down menu appears.
also the snmp query only work with direction input.

anyone can help ?

Since upgrading to 0.8.7a (Debian package) the grapsh are only using the "used real" stats.
I tried reimporting the latest version of the script, with the modifications to the script described above.
Any clue?

Hi

have you installed this patch : http://cacti.net/download_patches.php ?

"Graph Logic Syntax Issue"

Yes I did 2 days ago, as I saw this suggestion already on another post.

The snmpget results seem to be correct:

Code: Select all

/usr/share/cacti/site/scripts# snmpwalk localhost -c  xxxxxx-v1 .1.3.6.1.2.1.25.2.2.0
HOST-RESOURCES-MIB::hrMemorySize.0 = INTEGER: 1003904 KBytes

I've made another graph template set : http://forums.cacti.net/viewtopic.php?t=24501

Thanks! This one works great! And without needing a script, nice!

Graphs are messed up since upgrading to 0.8.7b (Debian package)

[fmangeant]

Hi

I've opened bug #1187

[Findarato]

This issue is with more than just this template, some of my squid graphs are now funky after going to 8.7b

[lauriou]

Since we updated to cacti 0.8.7.d, the output of the script netsnmp_memory_usage.php have strange behaviour:

With cacti 0.8.7.c:

Code: Select all

/usr/bin/php -q /home/reseau/cacti_old/scripts/netsnmp_memory_usage.php ...
totalReal:16301160 availReal:194896 totalSwap:20479992 availSwap:20479824 memBuffer:18456 memCached:15593124 usedReal:494684 usedSwap:168

With cacti 0.8.7.d:

Code: Select all

/usr/bin/php -q /home/reseau/cacti/scripts/netsnmp_memory_usage.php ...
totalReal:16301160 availReal: 194524 totalSwap: 20479992 availSwap: 20479824 memBuffer: 18504 memCached: 15593124 usedReal:495008 usedSwap:168

--> White space are added to the output after the colon of availReal, totalSwap, availSwap and memBuffer. In the RRD file, those values are NaN ...

Any idea to solve this issue ?.

Thanks

hello, I had exactly the same problem. It seems the new version likes to add white spaces somewhere and because of that the netsnmp_memory_usage.php file returns them too.

actually the fix is pretty simple - just trim them away.

I used php trim function for that :

the new output in netsnmp_memory_usage.php file :

Code: Select all

$output = $output . $oid[$outputcount][0] . ":" . trim($cmdoutput[$outputcount]) . " ";

the old output in netsnmp_memory_usage.php file :

Code: Select all

$output = $output . $oid[$outputcount][0] . ":" . $cmdoutput[$outputcount] . " ";

Voila and it started working again

[lauriou]

Hello,

You're right, the trim() function is a good solution.

Thanks !
