These are iPads and phones with their battery levels monitored in Grafana. How can I filter it, so it will show me the iPads only (starting with device name "H.") When I try regex like "/^H.$/" it doesn't work.
Thanks

Not a regex expert, but ^H.$
will only match H.
literally.
You need to match any amount and type of possible following characters as well; you can do that for numbers, lowercase, and uppercase characters with \w*
.
So in your case, ^H.\w*$
should work.
EDIT
After having a closer look at your pictures, I realize that the names you want to filter for are rows of the column device_name
, not the column names themselves. However, the used Filter by name
filters the column names, in your case device_name
and battery_level
. Since neither fit the regex, 'No data' is returned.
To filter the results of a column you have to use Filter data by values
. You have to specify the field, i.e. the column device_name
, use Regex
as type for Match
and then enter the regex in the Value
field.
Use the regex as explained above.
