Alert MySQL Last IO/SQL Errors when replication enabled

[brettlangdon]

This will send events when the MySQL slave receives a Last_IO_Error or Last_SQL_Error. It also tracks whether an error has occurred or not so it doesn't send events every time this check runs, just when the "status" changes (e.g. there is an error to there are no more errors).

The reasoning behind this is we have found with our MySQL slaves that sometimes they stop replicating when there is a IO or SQL error when replicating and we want a way to receive notifications when this happens.

Hey @DataDog can we get any movement on this? It would be very useful for us.

Hi Brett, Dan.
Thanks for this!

We are currently working on service checks that would be a more general solution for that kind of checks so we are not going to merge that in.

Maybe you could make a custom checks.d out of it so you won't be expecting the release of service checks ?

Thanks again for that and sorry for not merging that in.

Hey, any update about this functionality? We have also run into situations where we'd very much like to be notified upon error (this can happen due to timeout or some other exceptional circumstance). Simply notifying based on lag replication seems insufficient as the replication error is even more significant in certain cases.

Thanks

Sorry, just saw this: #671
