DBM CFG DIAGLEVEL Setting

I have had some recent engagements where someone set the DIAGLEVEL to 1 instead of the default 3. If not set to 3 you will miss many important entries that would have otherwise been written to the db2diag.log and you will not have the info you need to conduct problem determination efforts. You should keep it at 3 unless you have a real good reason to change it. Also, only ever change it to 4 for a short duration and when working with support. That’s the view from here. Stay tuned.
