We have some hosts where there are nested filesystems, e.g. /home
and /home/user
. The performance data is gathered and looking good.
However the service graph is only rendered for the innermost filesystem /home/user
. The outer filesystem only shows this error message instead of service graph:
Cannot calculate graph recipes
Syntax error in expression '('rrd', 'poke', 'enton', 'Filesystem /home', 'fs_used', 'max', 1048576),
('rrd', 'poke', 'enton', 'Filesystem /home', 'user_fs_used', 'max', 1048576),
('rrd', 'poke', 'enton', 'Filesystem /home', 'user_fs_size', 'max', 1048576),

('rrd', 'poke', 'enton', 'Filesystem /home', 'user_trend', 'max', 1048576),
('operator', 'MERGE')': too many operands left
This is even more baffling on another host with filesystems /home
, /home/mewtoo
and /home/ash
, where monitoring of /home/ash
is disabled by rule and /home/mewtoo
has been removed from the server (and monitoring). However the error message lists the deleted and the disabled filesystem as well.
We are using CMK 2.0.0b1 Raw Edition. I will provide more info on request.
