3.2.4
-
Ubuntu 16.10 running Zabbix Server 3.2.4 and Proxy versions 3.2.4 or 3.0.4
I have an issue where running a discovery is failing. This has been working for years. When looking at the host configuration > discovery there is the red "!" and it says "Value should be a JSON object." Every server, new or old, is now failing where it used to work.
Our script or agent config hasn't changed. I have recently updated the server and all proxies except 1 to 3.2.4. The discovery items are working on servers running under the one proxy that is still on 3.0.4.
I ran zabbix_get from the proxy to the servers to see what was being returned from the discovery, and it is in fact good JSON. I used an online validation tool to verify.
This is an example of the discovery that shows as failed from a 3.2.4 proxy:
$zabbix_proxy --version
zabbix_proxy (Zabbix) 3.2.4
Revision 65975 27 February 2017, compilation time: Mar 1 2017 04:52:47
$zabbix_get -s server1 -k hp.discovery[fans]
{
"data":
[
{
"{#FANNO}":"1_2",
"{#FANNAME}":"System board 1",
"{#FANTYPE}":"System board",
"{#FANVARSPEED}":"True"
},
{
"{#FANNO}":"3_2",
"{#FANNAME}":"System board 2",
"{#FANTYPE}":"System board",
"{#FANVARSPEED}":"True"
},
{
"{#FANNO}":"4_2",
"{#FANNAME}":"System board 3",
"{#FANTYPE}":"System board",
"{#FANVARSPEED}":"True"
}
]
}
And here is a discovery that is working from the 3.0.4 proxy:
$ zabbix_proxy --version
zabbix_proxy (Zabbix) 3.0.4
Revision 61185 15 July 2016, compilation time: Aug 6 2016 04:21:45
$zabbix_get -s server2 -k hp.discovery[fans]
{
"data":
[
{
"{#FANNO}":"1_2",
"{#FANNAME}":"System board 1",
"{#FANTYPE}":"System board",
"{#FANVARSPEED}":"True"
},
{
"{#FANNO}":"3_2",
"{#FANNAME}":"System board 2",
"{#FANTYPE}":"System board",
"{#FANVARSPEED}":"True"
},
{
"{#FANNO}":"4_2",
"{#FANNAME}":"System board 3",
"{#FANTYPE}":"System board",
"{#FANVARSPEED}":"True"
}
]
}
When compared, they are the exact same. The only difference is what proxy they are going through. Attached are screenshots of the failed and working configuration > host > discovery rules pages.
