Command macro to display process data from a set of processes
The other day I needed to trace all processes running the Apache web server. The processes all have the same name, httpd, which I thought would make it easy but it turned out not to be. There is an analyze_system request to execute a second request against all processes but not a subnet of processes. The following command macro provides that capability.
Usage
----------------------------- display_process_set ---------------------------- match_string: request_string_1: request_string_2: request_string_3: request_string_4: request_string_5:match_string
request_string_1
A string containing an analyze_system request to execute.
request_string_2
A string containing an analyze_system request to execute, it can be left blank.
request_string_3
A string containing an analyze_system request to execute, it can be left blank.
request_string_4
A string containing an analyze_system request to execute, it can be left blank.
request_string_5
A string containing an analyze_system request to execute, it can be left blank.
Notes
Output from each process is separated by a block of several lines of asterisk characters.
Timing is everything and it is possible for a process to terminate between the time that the process list is created and the requests are executed. When that happens you will see an error message "Process not found" and the previous process' data is displayed again.
This macro makes use of attach_default_output when creating the process list. If you terminate the macro while the list is being created you will have to manually execute the detach_default_output command.
This macro relies on the analyze_system prompt being "as: " if it has been changed you will need to adjust the macro. Also when run as a started process the macro turns off abbreviations. If the macro is run interactively you must be sure that none of your abbreviations overlap and commands or requests. I know that I can put an explanation point character (!) in front of the commands but that character can create problems when using the RSN software to transfer the macro so I don't use it.
Examples
Example 1
This first example matches on "http"; which is the first part of the process name "httpd". The request being executed is "trace". I have truncated the trace output to reduce the size of the example.

Example 4
While the command does execute interactively it typically generates a lot of output and I really expect that most of the time it will run as a started process. Don't forget to include the -privileged argument in the start_process command. This is needed to run analyze_system.

Including the match request in a started process is tricky because of the semi-colon. You can insert the semi-colon via the byte command function.
