Monitoring
The Monitoring feature allows Nodegrid to monitor and collect sensor data from Managed
Devices which are connected to a Nodegrid sensor or support SNMP or IPMI as a protocol.
The collected data are defined and controlled through
Monitoring Templates
which
will be assigned to a monitored device during its configuration.
Customizing a Monitoring Template
There are a number of pre-existing monitoring templates, which typically fulfill the user's
requirements. Should the need arise then these templates can be customized.
All templates are text files located in subdirectories of the
/etc/collectd.templates
directory according to the protocol used to collect the monitoring data, either SNMP or
IPMI.
/etc/collectd.templates/snmp
/etc/collectd.templates/ipmi
Any new file in these directories will automatically appear in the user interface.
SNMP Template
To create a new SNMP template, log in as root to the shell. Create a copy of one existing
template as a starting point for the new template.
Each SNMP template file has two types of subsections:
Data
One entry per data point, each identified by a unique ID.
Host
One single entry, defines SNMP parameters, the collecting interval, and which
data points are to be collected.
The template file should only include data points which are of interest, all other data points
can be removed from the file.
The following table explains the settings and the possible values for a data entry
