PMM-6811: Secondary lag reported as 136 years

v0.11.2

[0.11.2]

Added

• PMM-6361: New flag --suppress.collectshardingstatus can be used to disable the collection of Sharding Status. This flag is not set by default.
  On a large scale cluster it could help you to disable the mongoS exporters induced load to config tables. @vrazvan-adobe

Fixed

• PMM-6361: runtime error: invalid memory address or nil pointer dereference, source="sharding_status.go:166" .
  When chunks collection is very big, the aggregate on it can take longer then default default 1000ms SocketTimeout. @vrazvan-adobe

v0.11.0

Changed

• go.mongodb.org/mongo-driver was updated to v1.3.2.
• github.com/prometheus/client_golang was updated to v1.5.1.
• Skipping system dbs and collections.
• Those flags have been removed: --mongodb.authentification-database, --mongodb.max-connections, --mongodb.socket-timeout, --mongodb.sync-timeout. You can use connection-string-options instead.
• All mongodb_mongos_sharding_balancer_lock_* metrics won't be exposed for MongoDB 3.6+. See: https://docs.mongodb.com/v3.6/reference/config-database/#config.locks.

v0.10.0

Changed

• go.mongodb.org/mongo-driver was updated to v1.1.1.
