Errors and prompts seem to be piped in (e.g.: prompt for password)

Hey Baron,

I’m looking at both 2.0.4 and 2.1.1 and I see the query that uses innodb_locks similar to the one from the manual — That’s good to know. But I don’t see a second query on it.

Thanks for the response! I still like having the full output of the INNODB_LOCKS table =)

Ike, yes, thanks — I have those noted now.

Gavin, pt-stalk includes a query against those tables and stores the results into the TS-lock-waits file. Can you check that and see if it does what you need? If not, explain more? If you search the source for “INNODB_LOCKS” you will see we execute two queries agains the tables, actually.

I’ve made a note about having arbitrary collectors. Good idea.

We get a lot of requests to add features to disable binary logging. Through bitter, bitter, bitter experience we have learned that this is a sure way to completely destroy a percentage of users’ data. Did I mention “bitter” experience? Be careful what you wish for.
