== CCR
To view {ccr} metrics, click **CCR**. For each follower index on the cluster, it
shows information such as the leader index, an indication of how much the
follower index is lagging behind the leader index, the last fetch time, the
number of operations synced, and error messages. If you select a follower index,
you can view the same information for each shard.
shows the following information:
- **Index**: The name of the follower index.
- **Follows**: The name of the leader index.
- **Alerts**: Any read exceptions that have been triggered for the index or its
shards.
- **Sync Lag (ops)**: How many operations the follower index is lagging behind the
leader index.
+
This is calculated by finding the difference between the minimum and maximum operation
sequence number on the leader (`leader_max_seq_no`) and the difference between the minimum
and maximum global sequence number checkpoint on the follower (`follower_global_checkpoint`)
for each shard over the selected time period. The difference in `follower_global_checkpoint`
is subtracted from the difference in `leader_max_seq_no` for each shard, and the highest result
across all shards is displayed.
- **Last fetch time**: The time elapsed since the last successful fetch from the leader index.
Represents the longest time elapsed across all of the shards in the follower index.
- **Ops synced**: The number of operations indexed (replicated) into the follower index from
the leader index in the selected time period.
+
This metric is a sum of the number of operations indexed across all shards over the selected
time period.
- **Error**: Any exceptions returned for the most recent document in the selected time period.
If you select a follower index, you can view the same information for each shard.

If you select a shard, you can see graphs for the fetch and operation delays.
