How can the command line for the processes probe on Solaris be increased past 80 characters?
There is an option for solaris that can be set in the cfg file directly (raw configure or editor) called extended_cmdline in the setup section. It is a yes/no key. This will trigger an extra ps command which handles longer commandlines, and merges the data from the original ps command which truncated the commandline.
extended_cmdline = yes
This is also documented in the probe's readme file.
