ScriptServer Problem

Crescens · Post by **Crescens** » Tue Sep 21, 2004 1:37 am

Is anybody using the new Script Server?

I tried it yesterday, it worked fine if I used cactid directly. But when I tried to work with poller.php it grabs data but doesn´t update any rrd´s.

I spend some hours examing this but can´t find anything. I could not clear the Poller Cache, but maybe thats the problem described in this thread.
I took a look into the database and the scripts I saw that the table 'poller_output' was full of old entries. I flushed this table and suddenly cacti startet updating the rrd´s.

Is there anybody who can confirm this?
Or did I make a mistake and shot my database.

Current config:
cacti 0.8.6a <- downgrade not possible
RRDtool 1.0.48 <- fresh updated
PHP 4.3.8
NetSNMP 5.1

all on a Fedora Core 1 Box.

Use the latest pre-release from last night. There is an update that should correct your problem. You must run poller.php in your CRON. However, before you do this, you should disable your CRON, turn logging to DEBUG, clear you logfile, and run poller.php from the command line 1 time. You should see te CACTI2RRD and RRD2CACTI logfile messages on your screen.

There was a nagging RRD update problem that appears to have been corrected yesterday.

I use this one: cacti-0.8.6a-pre20040920.tar.gz
Last night ist difficult, we are 8 hours in front

You mean cacti-0.8.6a-pre20040921.tar.gz right? I´ll give it a try.

The debug worked fine, I saw a lot of CACTI2RRD and RRD2CACTI.

Can you give me a hint which Data Input Method "Get SNMP Data" and "Get SNMP Data (Indexed) " use? Was it "SNMP QUERY" or just "SNMP"?

I removed the changes I made for using the script server, that´s why I´m asking.

You are correct. This is the version to apply. I do not completely understand your other question. But in general, you should be using the "out-of-the-box" install. If you still experience issues, then we should continue to discuss changes/bugs.

Ok, pictures say more than 1000 words.
I´m not sure if I misconfigured this.
You see a red "arrow" in the picture?

There are the 2 items, I´m not sure if "SNMP Query" is right there.

You Data Input Methods should be as follows. Please ignore the duplicate on Script Server. I have a problem to fix.

Ok, I think the graphs are ok. No spaces anymore.

I tried also to activate the script server. It didn´t work for me again.
Now, I want to revert cacti to its original state.
Nearly everything is working, exept the php scripts which query processor and harddiskinformation (the two from the script server)

My debug log shows the following:

09/21/2004 04:25:01 PM - CMDPHP: Poller[0] Host[0] CMD: /usr/bin/php -q /var/www/html/cacti/scripts/query_host_partitions.php get total 101, output: U
09/21/2004 04:25:01 PM - CMDPHP: Poller[0] Host[0] WARNING: Result from CMD not valid. Partial Result: <br />
<b>Notice</b>

I switched back to cmd.php to. But I don´t think that matter.

/edit: I have to correct myself. Host[0] have to be an wrong entry.
I get no entry in the log file.
It seems that it doesn´t run the script.
I compared my old cacti installation with the new, but all data sources, data queries are the same

An idea where I can look?

Please reread the instructions, you missed a step and that is causing you problems. The script server does work.

Maybe, I think you misunderstand me.
Currently I want the original state back. The state before using the script server.
Ok, I´ll try it on my own.Thanks so far.

Host[0] means one of two things 1) You have non-host based queries (very old Cacti method) 2) You deleted a Host/Data Template and did not delete the Data Sources.

Item 2) is a very bad thing, especially to back off. It is crucial that you backup your database regulary. Say daily to minimize the risk of these configuration mistakes.

How would you classify your situation?
