I am trying community version Grafana 9.4.7 and working with Alerts and need to parse $value which is a string.
I need to perform string operations such as replace a string with another and so on.
Grafana templates what functions can be used? The only one i could use was slice. But functions like split, replace etc doesn’t seem to be available for me.

Hi @kmarrrahul, we recently updated the documentation for the latest Grafana version:

{{ title "hello, world!" }}
{{ toUpper "Hello, world!" }}
{{ toLower "Hello, world!" }}
{{ stripPort "example.com:8080" }}
{{ match "a.*" "abc" }}
{{ reReplaceAll "localhost:(.*)" "example.com:$1" "localhost:8080" }}
{{ stripDomain "example.com:8080" }}
{{ graphLink "{\"expr\": \"up\", \"datasource\": \"gdev-prometheus\"}" }}

{{ parseDuration "1h" }}

 {{ title "hello, world!" }}
  {{ toUpper "Hello, world!" }}
  {{ toLower "Hello, world!" }}
  {{ trimSpace "Hello, world!" }}
  {{ match "a.*" "abc" }}
  {{ reReplaceAll "localhost:(.*)" "example.com:$1" "localhost:8080" }}
  {{ join "-" (stringSlice "a" "b" "c") }}
  {{ safeHtml "<b>Text</b>"}}
  {{ stringSlice "a" "b" "c" }}

Hope it helps!
