[08:20:38] <Saw> hi, I'm looking for a way to do 'insert or merge' operation; anyone knows how can I do that? (that is, if document does not exists by some filter, insert it. If it does, set all non-null fields)
[12:18:01] <alexbevi> Was wondering if anyone could help me with some server performance issues
[12:18:10] <alexbevi> i've got a 3 node replicaset
[12:18:31] <alexbevi> we ingest a lot of data, and have some large processing scripts that run directly on the primary (javascript)
[12:18:59] <alexbevi> some nights we see the mongotop performance on the collections start to creep up really high (100000ms+)
[12:19:15] <alexbevi> and the replication lag goes a lot higher than usual
[12:19:25] <alexbevi> just looking for some troubleshooting ideas
[12:20:12] <alexbevi> if i do a rs.stepDown(); db.shutdownServer() on the primary and cycle the servers things will return to normal
[12:20:18] <alexbevi> but this happens every few days
