You can log in to zabbix web interface (same user as in script) and follow the following link to check the graph: <zabbix_url>/chart2.php?graphid=3123&from=now-1h&to=now&profileIdx=web.graphs.filter&width=900

Hi @zevilz

Yes, I see the graph at the link: zabbix/chart2.php?graphid=3123&from=now1h&to=now&profileIdx=web.graphs.filter&width=900

123

But through the script, now I get the following messages in the debug log:

[2023-04-04 11:22:16] Zabbix Telegram alertscript: [DEBUG] - Graphs enabled and graph data exists (graphData: graph:3123:1h:900; itemID: 3123; period: 1h; width: 900; height: )

@alexanderek, item ID not a graph ID. You check graph ID 3123 in browser and trying get graph for item 3123 :)

@zevilz Thanks for the tip, but now I'm back to the main issue:

@alexanderek, can you save file from browser on disk and show output for file <filename>

alexanderek commented 1 year ago 
$ file chart2.php.png 

chart2.php.png: PNG image data, 1016 x 368, 8-bit/color RGB, non-interlaced
zevilz commented 1 year ago

@alexanderek, try to remove > /dev/null 2>/dev/null on 204 line and test sending on test mode in zabbix web interface.

alexanderek commented 1 year ago

@zevilz Fixed. There was no file utility in the container. Thanks for the help!
