Cannot visualize Prometheus query result.

[Maltese-Falcon]

Dynamic Text v4.5.0, Grafana v9.3.2 (disable_sanitize_html = true) - cannot visualize query result.

Attempt 1, display without condition:

1. PromQL query A: sum by (system_name) (snmp_system_globalstatus{system_name=~"$host"})
2. PromQL query B: sum by (system_name) (snmp_power_state{system_name=~"$host"})
3. Under the transformation tab, merge the queries and validate that both are returned as a single row.
4. Reference in the Content section of the panel:

   <li>{{"Value #A"}}</li>
   <li>{{"Value #B"}}</li>

   No data. According to https://github.com/VolkovLabs/volkovlabs-dynamictext-panel/issues/23 that should work.

Attempt 2, display conditional content:

1. PromQL query A: sum by (system_name) (snmp_system_globalstatus{system_name=~"$host"}) == bool 3
2. PromQL query B: sum by (system_name) (snmp_power_state{system_name=~"$host"}) == bool 4
3. Under the transformation tab, merge the queries and validate that both are returned as a single row.
4. Reference in the Content section of the panel to display conditional content:

   {{#if (eq "Value #A" True)}}<img class="ok"/>{{else}}<img class="nok"/>{{/if}}
   {{#if (eq "Value #B" True)}}<img class="ok"/>{{else}}<img class="nok"/>{{/if}}

   That doesn't work.

@Maltese-Falcon Check the returned field names in Inspector or in the json output {{{json @root}}}. They may be called differently that what you are using.

[Maltese-Falcon]

Names are correct: { "data": [ [ { "Time": 1712172240000, "statusColor": "#73BF69", "system_name": "...", "Value #A": 1, "Value #B": 1, "Value #C": 1 } ] ] }

@Maltese-Falcon Did you select "Every Row" or other options?

Based on your output, you have data which indicates that you selected one of the other options. In this case you have to work with your fields using data as described in the documentation: https://volkovlabs.io/plugins/volkovlabs-dynamictext-panel/recipes/#iterate-through-all-fields-in-each-record

@Maltese-Falcon Please read documentation and watch videos to get familiar with the plugin

Thank you.

P.S.: I was able to display conditional content with Render template=Every row and after renamed fields with designations without spaces. I think this is something that should be included in documentation as a separate section.
