SoS performance scripts on AIX?

It appears that the built in ps_sos.sh and ps_lsof.sh scripts do not output any data on AIX.

Are the scripts any different from the ones that come with the *NIX app? Could the *NIX app scripts be substituted in?

As you have guessed, these two scripts are built on ps.sh and lsof.sh from the *nix app. However, the branch-off occurred before AIX support was added to the *nix app, which explains why ps_sos.sh and lsof_sos.sh don't work on AIX.

Integrating AIX support into those scripts shouldn't be a big deal. I have opened a requirement (internal reference: SUP-518) on your behalf to add this functionality to a future release of SoS.

The ps script from the *nix app didn't work on our AIX anyways. Back to square one.

I would rather recommend not doing so, although it might work. Our modifications to ps.sh mainly was to introduce an awk-based filter to restrict the output of the script to processes that only matched splunkd's and splunkweb's PIDs, as well as any search process. For lsof.sh, we added a similar level of scoping by providing splunkd's and splunkweb's PIDs as arguments to the lsof command.

The formatting (within the script) is a bit different, if i remember correctly. But you should be able to do a diff and see what those differences are between ps_sos and regular ps)

Can I drop the scripts from the current *NIX straight into SoS, or is the data format different?
