Append command results to an existing file

Use the -outa option when you want to append new command results to data stored in a previously written file. For example, at 11:00 A.M. you capture fan probe RPM readings for fan probe 0 on the system and write the results to a file called fans.txt. To compare these results with output for the same probe obtained four hours later, you can use the -outa command to append the new output to fans.txt.

Type:
omreport chassis fans index=0 -outa fans.txt
or
omreport mainsystem fans index=0 -outa fans.txt

Fans.txt now reads as follows:

Table 1. Append command results to an existing file. Append command results to an existing file.
Index : 0
Status : OK
Probe Name : System Board Fan 1 RPM
Reading : 2380RPM
Minimum Warning Threshold : 600RPM
Maximum Warning Threshold : 5700RPM
Minimum Failure Threshold : 500RPM
Maximum Failure Threshold : 6000RPM
   
Index : 0
Status : OK
Probe Name : System Board Fan 1 RPM
Reading : 3622RPM
Minimum Warning Threshold : 900RPM
Maximum Warning Threshold : 3500RPM
Minimum Failure Threshold : 500RPM
Maximum Failure Threshold : 6000RPM

You can use a text editor to insert the time that each block of data was captured. In comparing the two snapshots for fan probe 0, you can see that the second report shows several changes. The reading of fan RPM has increased by 621 RPM but is still within normal range. Someone has raised the minimum warning threshold by 200 RPM and has decreased the maximum warning threshold by 2000 RPM.
