Cacti poller ?

[chunkd]

Hey,

Just need some information, I have searched high and low and read the cacti manual with no luck.
So here's my ?

There are 2 types of pollers within cact poller.php and cactid. What is the difference ?????? Can someone please clear this up.

As far as I know, the cactid poller is quicker thtn poller.php?? Is this true?


Thanks

cmd.php, as the name implies, is a PHP script. It's interpreted and has all the overhead associated with PHP. It's suitable for deployment with few devices. I am currently polling 13 devices (3 local, 10 remote) and cmd.php is taking ~40 seconds to run. Fine if you ask me.
cactid is an executable, i.e. program. It's compiled and as such is faster than cmd.php, making it the ideal choice for environments with many devices. I don't know how many devices you can handle with one or the other, but if you begin to feel that cmd.php is taking too long, try cactid and check the log to see the difference.
On my notebook, where I do development, I have 3 devices (2 local, 1 remote). cmd.php takes 4 seconds to run, cactid takes 8.7. So each of them has its role - it depends on your environment. Regards,

I am disturbed that Cactid is taking that long. I have seen this as well in the Windows environment on XP Pro. It started after some Microsoft patch. When I open a bash shell and run it, it only takes 2 seconds. When I use the task scheduler, it takes from 7 to 13. Go figure.

Anyway, to guage performance, see this article.

Hi,

I'm trying the cactid poller in stead of the php poller, however, I get following error :

D:\cactid>cactid
CACTID: Using cactid config file [cactid.conf]
CACTID: Version 0.8.6e starting
CACTID: ERROR: Problem initializing SNMP session 'HOSTENAMEDELETED'
CACTID: WARNING: Unknown host HOSTNAMEDELETED
6 [unknown (0xB34)] cactid 3096 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
10110 [unknown (0xB34)] cactid 3096 open_stackdumpfile: Dumping stack trace to cactid.exe.stackdump


the HOSTNAME is reachable and resolvable, SNMP settings should be fine

I'm running Cacti on the following configuration :

Windows 2003 Server SP1
Mysql 4.11-NT
PHP 5.0.4



any ideas?

hmmm it seems I'm getting somewhere ....

now it runs for 2 (of the 6 devices)
and it ends with the following few lines


No log handling enabled - turning on stderr logging
read_config_store open failure on /var/net-snmp/cactid.conf
read_config_store open failure on /var/net-snmp/cactid.conf
read_config_store open failure on /var/net-snmp/cactid.conf
CACTID: Execution Time: 10.6140 s, Threads: 10, Hosts: 8
------------

as said... I'm running on W2K3 platform...
is this something I need to concern about? if so.. where can I change the setting so it poitns to D:\cacti

I have released Cactid 086-rc12 for testing. Give it a whirl.

is it posible to have it compiled for windows platform?

Done already. You must have cygwin installed however.

Anymore on the following cactid error?

read_config_store open failure on /var/net-snmp/cactid.conf

I just updated my cacti and cactid installation to the latest stable versions today. So far the install went smooth but my automatic updates have ceased. I see that error pasted about when I run cactid manually.

The graphs do update if I run poller.php manually, I just cant go with that option in an automated fashion since im polling 167 devices loaded with 24-48 interfaces each.

btw... heres a cactid poller benchmark for ya... I cant even get the cmd.php to finsish so no benchmarks there.

relative to config store, what version of net-snmp?

TW

[bitgod]

net-snmp-5.1.2-11 Running on CentOS 4.2.

Poller locked up on me yesterday apparently. Had to kill a couple processes, clear poller cache. Then noticed this:

-sh-3.00$ cactid
CACTID: Using cactid config file [/etc/cactid.conf]
CACTID: Version 0.8.6f starting
File size limit exceeded
-sh-3.00$ php cmd.php
File size limit exceeded

Cacti was spooged so I copied /dev/null to cacti.log since the web page quit loading.. then cactid would run again. Went back and lowed error log level. Not sure what started this. never had the log filling that much before while I didn't change the log level when I upgraded. All appears well again.

Your cacti.log file is too big. Please implement management such as logrot. Also, to get rid of the net-snmp message, please upgrade to 5.2.x.
