error in zabbix_agent log file

[Trikke76]

Hi,
Nice script for zabbix
in our setup it seems to work fine however
in the agent log there are errors on all elasticsearch nodes

return json.load(open(cache))
File "/usr/lib/python2.7/json/init.py", line 278, in load
*_kw)
File "/usr/lib/python2.7/json/init.py", line 326, in loads
return _default_decoder.decode(s)
File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python2.7/json/decoder.py", line 384, in raw_decode
raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

raise ValueError("No JSON object could be decoded")

this happens on ubuntu 12.04

I'm seeing this also -- here's an example from the zabbix server log:

13966:20160916:114202.405 item "scmon-es1:elastizabbix[nodes,nodes.8r_wOHz-SvO9_bX8cmny5g.breakers.fielddata.tripped]" became not supported: Received value [Traceback (most recent call last): File "/etc/zabbix/externalscripts/elastizabbix.py", line 76, in stat = get_stat(api, stat) File "/etc/zabbix/externalscripts/elastizabbix.py", line 44, in get_stat d = get_cache(api) File "/etc/zabbix/externalscripts/elastizabbix.py", line 41, in get_cache return json.load(open(cache)) File "/usr/lib64/python2.7/json/init.py", line 290, in load **kw) File "/usr/lib64/python2.7/json/init.py", line 338, in loads return _default_decoder.decode(s) File "/usr/lib64/python2.7/json/decoder.py", line 365, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib64/python2.7/json/decoder.py", line 383, in raw_decode raise ValueError("No JSON object could be decoded") ValueError: No JSON object could be decoded] is not suitable for value type [Numeric (unsigned)] and data type [Decimal]

What's happening is that elastizabbix script is occasionally generating python errors which are being sent from zabbix agent to zabbix server as the script return value. The zabbix server is (correctly) saying that the python error output is not compatible with the data type (unsigned) expected...

Why elastizabbix is throwing errors and why zabbix agent is passing them to the server... I have not figured out yet.

Looks to me that you're not getting valid responses back from elasticsearch:

ValueError("No JSON object could be decoded")

It very well could be because of a timeout situation if your elasticsearch nodes are responding slow. Try adding "timeout=150" to this line:
https://github.com/mkhpalm/elastizabbix/blob/master/agent/elastizabbix#L37

And make sure you increase your zabbix agent conf file's Timeout setting to match.

If you are not using http://localhost:9200/ as backend server address. you should modify
