No data when querying custom item defined by User Parameter

[grafoo]

when i try to create a graph from a custom item ( datasource is a command defined by a user parameter ) nothing will be plotted.
also tables and other types of panels are not working.

Do you see this metric in zabbix?

[grafoo]

Yeah. In zabbix itself it works alright. Can i somehow turn on logging in your plugin?

[alexanderzobnin]

Can you look at browser network requests in dev tools? What zabbix api return.

[grafoo]

good idea!

a successful api query will look like this
request

'{"jsonrpc":"2.0","method":"history.get","params":{"output":"extend","history":"0","itemids":["11111"],"sortfield":"clock","sortorder":"ASC","time_from":1458182849,"time_till":1458204449},"auth":"someauthtoken1234","id":1}'

response
the resultset will have an array of the following entries:

{"itemid":"111111","clock":"1458182870","value":"0.0112","ns":"839060550"}

when querying the custom item, it will look for all items of a given host matching value types from 0 to 3
request

'{"jsonrpc":"2.0","method":"item.get","params":{"output":["name","key_","value_type","delay"],"sortfield":"name","webitems":true,"filter":{"value_type":[0,3]},"monitored":true,"searchByAny":true,"hostids":["99999"]},"auth":"someauthtoken1234","id":1}'

response
the response will have an array of those items e.g.

{"itemid":"22222","name":"$1 service available","key_":"net.tcp.service[ssh,,22]","value_type":"3","delay":"30","hostid":"99999"}

maybe it is important to know that the items where the query isn't working where created using low-level discovery?

[grafoo]

i guess it's slightly different than i first anticipated.
you're using

'{"jsonrpc":"2.0","method":"item.get","params":{"output":["name","key_","value_type","delay"],"sortfield":"name","webitems":true,"filter":{"value_type":[0,3]},"monitored":true,"searchByAny":true,"hostids":["99999"]},"auth":"someauthtoken1234","id":1}'

for discovering all supported items by the host right?

so in this case when selecting the item which isn't working, grafana simply doesn't not send the additional request to get the values if the item.

[alexanderzobnin]

What version of Zabbix do you use?

[grafoo]

2.0.16

[alexanderzobnin]

I need to check api details for 2.0. It's very old version, and it may have some differencies from 2.2 and 2.4.
