About Dependencies
Most of the check_netapp_pro check-scripts get their data from a local
store-file, which is written by a collector (also known as
getter due to their file-name get_netapp*.pl).
The getter-scripts are configured in the monitoring-system and run as if
they were normal service-checks.
Some very simple checks do not require any collector. They run like a traditional stand-alone plugin and retrieve their data directly from the filer.
Please keep in mind that all checks from the Performance-Bundle get their
data trough a special performance-data getter
(get_netapp_perfdata.pl).
Examples
Some examples which show how the data for specific checks gets collected. The relation between the check and the object is fully documented in the table below.
Example 1: Single Dependency
The following example shows which getter must have been run so that the Usage of volumes can be checked on a cluster-mode filer:./get_netapp_cm.pl -H my_cdot_filer --object=volumeSame as above but for a 7-mode filer:
./get_netapp_7m.pl -H my_7m_filer --object=volume
Example 2: Performance Data
To check the per volume latency (PerfVolume) the performance-getter must have been run (at least twice) configured with the correct object and mode as shown below:./get_netapp_perfdata.pl -H my_cdot_filer --object=volume --mode=cm
Example 3: Complex Dependency
Some checks need the data from more than one object. The following example shows the requirements to monitor the overcommitment of aggregates with the check OvercommitAggr:./get_netapp_cm.pl -H my_cdot_filer --object=volume ./get_netapp_cm.pl -H my_cdot_filer --object=aggregateThe next example shows the requirements for checking Snapshots. Here we also see that the objects data must be either retrieved by the generic getter
get_netapp_cm.pl or in some cases
with a specialized getter for that object like get_netapp_snapshot.pl.
./get_netapp_cm.pl -H my_cdot_filer --object=volume ./get_netapp_snapshot.pl -H my_cdot_filer # the snapshot-object has its own getter
Dependencies by Bundle and Check
This table lists all dependencies between checks and getters. If no dependency is listed the check is a traditional stand-alone check.
