Cactid

Witness / Rax,

I am running cactid on XP. I can run it fine with 1 thread but it runs slower than the poller.php set to cmd. When I increase the threads to 2, I start getting these messages:

10/13/2004 07:50:20 AM - CACTID: Poller[0] Host[27] WARNING: Result from SNMP not valid. Partial Result: U...
10/13/2004 07:50:20 AM - CACTID: Poller[0] Host[26] WARNING: Result from SNMP not valid. Partial Result: U...

Any hints on how to resolve this issue?

Regards,

Willie

Manually poll and/or varify the two OIDs that are failing, are valid.

Thanks for the reply. I am running cactid with 1 thread and it works fine. I ONLY get those messages if I up the thread count. 1 thread on CactiD work about the same speed as the php poller.

Regards,

Willie

Set logging to DEBUG and post your results from 1 poll cycle. Also, please download the CVS copy of CACTID 0.8.6c and try it. If you are polling the same IP address as multiple hosts, some SNMP hosts can't handle the volume of traffic comming from net-snmp.

For example, my test system has 4 hosts:

IP Address Hostname
192.168.0.2 BASEMENT1
192.168.0.2 BASEMENT2
192.168.0.2 BASEMENT3
192.168.0.2 BASEMENT4

As you can see, they are the same system. Things are pretty good until I add the 5th host, then things start to break.

I have found the following, related to 'Result from SNMP not valid. Partial Result: U... '-problem :

* when Maximum Threads per Process for CACTID is to high, you get these SNMP errors. I mean : first had 4 cactid threads -> had sometimes these SNMP errors ; then tried 8 cactid threads -> a lot of SNMP errors ; then tried 2 cactid threads --> NO SNMP errors !!!

* I get these SNMP errors only on Netware servers. All NT servers are polled correctly!

Maybe this info helps you, TheWitness ?!

Am I the only one with these kind of problems, or is this indeed a problem with cactid?!?

tapufd,

I have sent logs of a good run (1 thread) and a bad run (2 threads) to the Witness with full debugging info. They are looking at it.

Regards,

Willie

This should work in Unix no problem. Concerned about pipes in Windows, but should work. Test, then post. If no lockups, I will commit to CVS.

Witness,

This has solved my "WARNING: Result from SNMP not valid. Partial Result: U... " errors.

With 1 thread, cactid is slower than the php cmd. But, with 10, I drop from 174 sec to run (461 hosts 3100 interfaces) to 48 secs!

Regards,

Willie

Hi TheWitness,

It also solved my 'Partial Result: U...' errors. Thanks!

Question: during a period of 24h polling, I had twice 'Dead Lock' in my cacti.log. Is this something serious or can it be ignored?

Many, many thanks.

Hello TheWitness,

See in attachment my log file. It's not in DEBUG mode, so i think it won't help that much. Maybe you can look at it and see what you can learn from it.
- It seems that I sometimes still have 'Partial Result: U...' errors.
- You can also find the 'Deadlock Occured' errors.
- Also sometimes 'The PHP Script Server Did not Respond in Time' errors.
If a log in DEBUG mode is necessary, please tell (problem will be that the log will be very big).

When browsing Cacti, my connection with MySQL is sometimes broken for a few seconds. When I press the refresh button, I get the webpage OK.
This is the error I get in IE :
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'localhost' (10048) in D:\Cacti\Website\lib\adodb\drivers\adodb-mysql.inc.php on line 324
Cannot connect to MySQL server on 'localhost'. Please make sure you have specified a valid MySQL database name in 'include/config.php'.

I'm using mysql-4.0.20d-win for the moment. Should upgrading to latest mysql-4.0.21-win, solve this problem?

I am getting the same thing with the errors. I have recently upgraded my server from an old laptop to a DL580 Dual Processor server. I am able to run the cmd version of poller but everytime I run cactid, I get the "cannot connect to mysql". I get this even if I reduce the thread count to 1. the higher the threads, the faster I get the errors.

Regards,

Willie

Guys, this is the latest and greatest not submitted to CVS. Also, increase your SNMP timeouts and retries, especially if you are getting problems with "U" results.

I am going to not provide every warning in 0.8.7 at LOW or below, I will simply provide counts because this error can be expected from time to time. You definately need to increase your timeouts though.

Let me know how it goes.
