Win32 - Monitor running processes

mutha · Post by **mutha** » Mon May 23, 2005 10:39 pm

I may be missing something here, but I followed these instructions

By default, the index type will use 'hrSWRunIndex'. This number is the same as the PID in process manager.  You want to change it to use 'hrSWRunName' for each process.  Type in the executables name (i.e. winamp.exe).  You can find the name at top of the screen for the process you're working on (i.e. computername - process - processname

and upon restarting a process and picking up a new PID Im getting error messages on the processes that were setup previously when poller.php runs thus no new data to graph.

I can remove the data sources and add them back and everything will work until the next restart.

thanks in advance

You're saying you close a process, reopen it, and the data source is no longer valid? The only time the new PID is by default reindexed is when the number of processes changes. If this creates a problem, then you can change the reindex method to 'verify all fields'.

I have a fix for this.... It's not free, requires lot's of Atkins Coockies & Cream bars

I'll give it a try thanks.

Witness, be careful with those Atkins delights, they tend to run straight thru you

Code: Select all

Yes.. Tried the verify all fields>> didnt work for me

What is happening is although I am using run name for the data source, when poller.php runs it is still looking for original PID number.

I have also found that if I remove all of the data sources that I had setup (relative to this plugin) the nextime I add a new data source poller is trying to locate all of the previous PIDS I had setup before.

I am thinking "cache problem" because when I click clear poller cache from the Cacti System Utilities menu nothing happens. The same data is still there. Could be a separate issue. I am still learning

Here you go Witness

1) the fix TheWitness is talking about will come in Cacti 0.8.6e by adding <index_type>nonunique</index_type> to the xml.

2) It sounds like you did not change the datasource hrSWRunName and the process name you want to monitor.

The only time Cacti will reindex the processes (aka refresh the PIDs), is if the number of them changes between polling cycles. When that happens, you'll see something like this in the log: CMDPHP: Poller[0] ASSERT: '40=36' failed. Recaching host 'gamerxp.zeus.xxx.com', data query #14. The <oid_num_indexes> line in win32_procs.xml triggers this.

So if a process closes and reopens again, resulting in the same number of processes, Cacti will not (currently) refresh the PIDs. I though changing the polling method to 'verify all fields' would've force cacti to do this.

I wish I could just reach out and eat that thing! BSOD is correct. CVS has changed significantly due to a security flaw, so just be patient.

Has anyone gotten this script to work using the cactid poller? I'm using the 0.8.6.d version

BSOD2600 · Post by **BSOD2600** » Mon May 30, 2005 12:34 pm

I don't (can't) use cactid. What errors are you getting?

elnino · Post by **elnino** » Mon May 30, 2005 12:56 pm

No errors are shown on Low logging, but the graph doesn't show any data for the memory usage. If I put it on Medium logging here's what it pulls back:

Code: Select all

Also, I switched out the functions.php that you said to a few posts up but that didn't help any.

BSOD2600 · Post by **BSOD2600** » Mon May 30, 2005 10:58 pm

You must be running linux and/or net-snmp. Read the first post, there is a fix for not displaying the kbytes.

elnino · Post by **elnino** » Tue May 31, 2005 8:23 am

Yes, I am running Linux with net-snmp and I already tried replacing the functions.php with the one from the other thread.

That patch only works with cmd.php. I have to make Cactid 0.8.6e-rc11

It seems i havent the right mib ... how to fix that ?

CactiPadawan · Post by **CactiPadawan** » Wed Jun 15, 2005 3:47 am

No one can help me ? I need to know what is the right mib to use and where to download it please.

Most template present in cacti use OID that arent present in the mibs installed by default in net-snmp it seems .. or maybe i did something wrong.

From what i can read here : http://www.net-snmp.org/docs/README.agent-mibs.html

UCD-SNMP-MIB and HOST-RESSOURCES-MIB

(the mibs you are using with your scripts)

are not working for Win32 based Platforms . . .

This readme says too that "The OS platform is probably the least reliable of the columns" ok but when i try a snmpwalk on my Win XP there is no OID associated with HOST-RESSOURCES-MIB or UCD-SNMP-MIB (or juste FileTable..) ... if i try with snmpget on a the OID you use in your scripts i have no result.

If i try the same (snmpwalk / snmpget) on a Linux based machine i can gather all the informations...

So it seems that i havent the right mibs installed
i read that file http://www.net-snmp.org/docs/FAQ.html#H ... _the_agent_
and i would like to know what kind of method you used to add a MIB that work with Win32 based platform ....

Please help ^^

Thank you in advance
