ifx_concurrent_sessions_ - Munin wildcard plug-in that connects to Informix instance and counts number of concurrent sessions from syssqlstat view of sysmaster of instance.
Connects over the network to Informix databases. Uses informix commands to connect to the databases so these must be present on the munin-node it runs on.
As Informix installations can vary wildly the autoconf may fail. However, it is recommended to let munin-node-configure set the plugin links by e.g.
# @@SBINDIR@@/munin-node-configure --families contrib --shell | grep concurrent | sh -
Yet, for this plugin to work it is most likely required to grant select to the user the munin-node runs this plugin as. This usually requires to login as user "informix" and execute the following command:
$ echo "grant select on syssqlstat to munin as informix" | INFORMIXDIR=/path/to/ifx_base INFORMIXSERVER=inst_name dbaccess sysmaster
The value of INFORMIXSERVER usually equals to that of DBSERVERNAME in the $INFORMIXDIR/etc/onconfig file.
This plugin hangs during autoconf - at least on systems without informix. Therefore capabilities magic marker has been removed.
May not autoconfigure correctly as noted above.
