Can we add the exim queue size to the grafana graphs for mail. it look slike the current metrics are derived using mtail so will not be able to collect the active queue size as such some other tool will likely be required.
would be good to split the graph by
frozen: exiqgrep -z -c
unfrozen: exiqgrep -x -c
total: exiqgrep -c
worth noting all theses values can be derived from the same command e.g.
$ exiqgrep -x -c 830 matches out of 1721 messages
1721: total messages
830: unfrozen messages
891: frozen messages (1721-830)
