Dashboard

Dashboard is a self-monitoring page that comes with LinDB, the internal real-time status of each component is available in the relevant dashboards

Replication

Database replication status mainly includes the following status:

  • Basic state information of the database, such as the number of replicas;
  • Replica distribution and replication status, such as channels delay information;
  • Local replication write.

WAL

There are 2 modes viewing replica status, which can be switched through the button on the right side of the Replication State:

  • Mode 1: Perspective of the distribution of replicas in each Storage node, and show whether there is a replication delay, mouse hover to a shard will display replication of each channel in it;

Replication shardsReplication shards

  • Mode 2: Perspective of replication channels under all shards, Shard/Family related filtering and filtering is supported

Replication familiesReplication families

Write

Write status of the local replica:

  • Write status of each memory-database;

  • Each leader's writing pointer status;

  • Mode 1: Perspective of writing status of all memory databases under all shards, Shard/Family related filtering and filtering is supported

Memory database writeMemory database write

  • Mode 2: Perspective of all active families under all shards, Shard/Family related filtering and filtering is supported
