Can Postgresql alert with Image?

Hello all,
I’m trying to create alert with image and got error :

error:“tsdb.HandleRequest() response error &{error parsing interval $group_time A 0xc42034d2e0 [] []}”

I’m using Postgresql and Grafana v5.2.0-pre1 (5a2cf58) .
My sql query :

SELECT $__timeGroup(“timesys”,group_time), COUNT (userid ) as "Total file" FROM tbl_monitor_handle_file WHERE __timeFilter(timesys)
GROUP BY time
ORDER BY time

Please help me if you have any suggest.
Thanks

Alerting doesn’t support template variables. Replace group_time with an actual value. Besides that you should be able to use alerting with images given that you configured notification channels and image storage (if notification channel requires it).

thanks @mefraimsson . I will try other way.
