To capture resource monitoring
data from UNIX rstatd, you must
configure the data source. UNIX rstatd is bundled with most Linux distributions.
Before you begin
To collect resource monitoring
data from UNIX rstatd, the portmapper
service must be enabled on the host computer. To determine whether
the portmapper service is enabled, type the following on the command
line of the host computer:
rpcinfo -p localhost
The portmapper service is listed in the output of the rpcinfo
command. If it is not, contact your system administrator for help
with installing or configuring the portmapper service.
Procedure
- On the Resource page, select the type of data that you
want to capture. The tree view shows all available performance counters,
with a default set of counters preselected. To see all available counters,
clear the Show only selected counters check
box. Be selective; monitoring all possible resource data
requires substantial amounts of memory. Hold your mouse pointer over
a counter to see details about what that counter measures.
- Configure connection information and time intervals on
the Options page.
- Change the Connection information
if needed. Typically, you need to change this information only if
a firewall is blocking the default port.
- Type the Polling Interval in
seconds, for collecting resource data. For example, if you accept
the default of 5 seconds, counter information will be collected at
5-second intervals from the specified host during the schedule run.
- Type the Timeout Interval in
seconds. If the resource monitoring host does not respond within this
amount of time during a schedule run, an error is logged.
