MongoDB Troubleshoot:
- mongostat:
mongostat --username admin --password <password> --authenticationDatabase admin --ssl --sslAllowInvalidCertificates 2
- mongotop:
mongotop --username admin --password <password> --authenticationDatabase admin --ssl --sslAllowInvalidCertificates 2
- check mongod log for slow queries (MongoDB community):
oc logs -n <mongo namespace> <mongo pod name> -c mongod | grep -iE 'Slow query'
- long connection over 3 seconds:
db.currentOp({"active" : true,"secs_running" : { "$gt" : 3 },"ns" : /^msg/})
- kill long running connection:
db.killOp("opid")
- locking:
db.serverStatus().globalLock
- mem:
db.serverStatus().mem
- wiredTiger cache:
db.serverStatus().wiredTiger.cache
- concurrent:
db.serverStatus().connections
