Problems with custom script

breakintheweb · Post by **breakintheweb** » Wed May 17, 2006 9:46 pm

I wrote a custom script that outputs the following

Baseboard_Temp:25
FntPnl_Amb_Temp:17
Power_Cage_Temp:27
Processor1_Temp:22

I created a datasource using my custom script but am unable to get the rra file to create. I've read the manual, that refers to this process but am still unable to get it working. Can any one point me in the right direction?

First, all output parms must be on the same print statement, no CR/LF. Second, follow the second to last link of my signature for a walkthrough of the steps that should be performed to get this up and running

I changed my data output to:

Baseboard_Temp:26 FntPnl_Amb_Temp:16 Power_Cage_Temp:27 Processor1_Temp:22

the rra and graph is being created but the values are nan. Also, can cacti automap the value such as names (Baseboard_Temp) when polling.? Every cacti example i've see so far inputs values only and the values then get mapped to names through the cacti interface.

Mapping to rrd data sources is done by the definitions made for your Data Template (as described in my howto. If it is not clear enough, please give me a hint about the missing info to improve it). When running in DEBUG mode, the poller logs it (search for "map" in ./log/cacti.log)
If in doubt, please post a screenshot of the lower part of the Data Template

I'm confused about the "use data-source value" is this how i get cacti to use the ds name from the script output?

I turned on log debugging and the below is what is said for my data gathering.

05/18/2006 04:53:53 PM - CMDPHP: Poller[0] Host[4] No host availability check possible for '192.168.0.5'.
05/18/2006 04:53:53 PM - CMDPHP: Poller[0] Host[4] DS[29] CMD: /var/www/html/scripts/check_ipmi.php 192.168.0.5, output: Baseboard_Temp:26 FntPnl_Amb_Temp:17 Power_Cage_Temp:27 Processor1_Temp:23

Once again, thanks for your help

The script seems to be ok. But the Data Template does not map your script, in not a single data source.
Please build a new Data Template. Name it IPMI Template or the like. Choose Data Input Method = YOur script.
Name the first data source like the first output parm of your script and select the same from the Output Field dropdown. Now select New to create a new data source. Enter the second output parms name as a data source name and select again the appr. Output Field. Repeat this for the last two output parms. All in alll, that's the procedure described in my howto, but repeated for all 4 output parms.
Now create the Graph Template referring to the newly created data sources. Again, refer to my howto but repeat the procedure for all of the 4 output parms.
BTB: You did discover the already existing IPMI Templates in the Scripts and Templates Forum?

I have taken a look at the posted ipmi script but it was extremely slow and i couldn't get it to work in cacti. I plan on releaseing my script here one it works

I redid everything and now the rrd file isn't creating.

I really don't understand what i'm missing?

Well, this looks by far better now. Took a time to figure out, what the TEMPx would relate to.
Next step: Please check the host's status when looking at the Device list. Should be up. And when editing the host, no red SNMP error should be seen. Please confirm both to proceed to the next debugging step.

The host is up under devices (i'm using icmp for downed host detection) when i click on the host i get a red SNMP not in use

As I don't know anything about your script: Does it use SNMP? Or do you intend to use SNMP for the target in question? If not, leave the community string of that host's definition empty. I suppose you already did so.
Then, please login as cactiuser and run the

Code: Select all

php poller.php

manually from cacti's directory. Watch out for errors. You may switch Settings->Logging Level to DEBUG for one polling cycle and rerun the poller manually. Please post your findings

THe script runs fine from the console. I have cacti running as root and the script set to 777 just to make sure.

Umm, if your script is outputting: Baseboard_Temp, FntPnl_Amb_Temp, Power_Cage_Temp, Processor1_Temp, then those are the names you should be using in the data input methods Output fields. Cacti is looking for "temp1" etc which of course your script doesn't output.
