UserParameter not sending data to items in frontend

[jab2805]

Hi all,


I have been trying to setup a UserParameter to watch a log file for the string ERROR.


ENV:

Zabbix server 1.8.3

zabbix_agentd:

ZABBIX Agent (daemon) v1.6.1 (04 November 2008)
Compilation time: Apr 20 2010 19:40:47


Setup:


UserParameter=fastchecklog.status,cat /home/fastuser/fastcheck/check_datestamp.log|awk '{print $3}'| grep ERROR


1. I restarted zabbix_agentd.

2. Set debug level to 4 in /etc/zabbix/zabbix_agentd.conf.


3. Tested successfully my key from the zabbix server using zabbix_get:

$ zabbix_get -s nyss0223 -p 10050 -k fastchecklog.status
ERROR
ERROR
ERROR
ERROR
ERROR
ERROR
ERROR

4. On the client I tested using zabbix_agent -t:

zabbix_agent -t fastchecklog.status
fastchecklog.status [t|ERROR
ERROR
ERROR
ERROR
ERROR
ERROR
ERROR]

5. I configured the following item setting

Host=xxxx
Description=fastchecklog.status
Type=Zabbix agent
Key=fastchecklog.status
Type of information=Text
Update interval(in sec)=60
Keep history(in days)=7



The item is not updating with any data when I check Monitoring | latest data.

What could the issue be?

First question how long does it take to parse the data? If it's taking too long to gather you might need to look at using a different method instead of using a userparameter.

UserParameter=fastchecklog.status,cat /home/fastuser/fastcheck/check_datestamp.log|awk '{print $3}'| grep ERROR

Also good practice when using positional references you should use $$.

UserParameter=fastchecklog.status,cat /home/fastuser/fastcheck/check_datestamp.log|awk '{print $$3}'| grep ERROR

You may be running into an issue with a multi-line response.
If you are want to capture the string data and you want to put it on one line you can do something like:
UserParameter=fastchecklog.status,cat /home/fastuser/fastcheck/check_datestamp.log|awk '{print $$3}'| grep ERROR | awk -vORS=' ' 1

If you are only capturing the word ERROR for how many times it occurs it maybe more efficient to just do a grep count so then you are sending a single numeric value to zabbix.

UserParameter=fastchecklog.status,grep -c ERROR /home/fastuser/fastcheck/check_datestamp.log
or
UserParameter=fastchecklog.status,cat /home/fastuser/fastcheck/check_datestamp.log|awk '{print $$3}'| grep -c ERROR

Thanks justinc,


Because its a grep of the file I don't think the time is that long. I tried all of the above changes, but my items are still not getting any data. I changed the item type from char. to dec. since I'm now send a numeric values. One odd thing I notice is when I run zabbix_agent -t key I still get string data retuned; I was expecting numeric data, however zabbix_get from the zabbix server returns the expected data type.


1.
zabbix_agent -t fastchecklog.status
fastchecklog.status [t|ERROR
ERROR
ERROR
ERROR
ERROR
ERROR

2.
zabbix_get -s nyss0223 -p 10050 -k fastchecklog.status
