Metric |
Description |
---|---|
scylla_column_family_tablet_count |
Tablet count |
scylla_cql_replication_strategy_fail_list_violations |
Counts the number of replication_strategy_fail_list guardrail violations, i.e., attempts to set a forbidden replication strategy in a keyspace via CREATE/ALTER KEYSPACE. |
scylla_cql_replication_strategy_warn_list_violations |
Counts the number of replication_strategy_warn_list guardrail violations, i.e., attempts to set a discouraged replication strategy in a keyspace via CREATE/ALTER KEYSPACE. |
scylla_load_balancer_resizes_emitted |
Number of resizes produced by the load balancer |
scylla_load_balancer_resizes_finalized |
Number of resizes finalized by the load balancer. |
scylla_reactor_fstream_read_bytes_blocked |
Counts the number of bytes read from disk that could not be satisfied from read-ahead buffers, and had to block. Indicates short streams or incorrect read ahead configuration. |
scylla_reactor_fstream_read_bytes |
Counts bytes read from disk file streams. A high rate indicates high disk activity. Divide by fstream_reads to determine the average read size. |
scylla_reactor_fstream_reads_ahead_bytes_discarded |
Counts the number of buffered bytes that were read ahead of time and were discarded because they were not needed, wasting disk bandwidth. Indicates over-eager read ahead configuration. |
scylla_reactor_fstream_reads_aheads_discarded |
Counts the number of times a buffer that was read ahead of time and was discarded because it was not needed, wasting disk bandwidth. Indicates over-eager read ahead configuration. |
scylla_reactor_fstream_reads_blocked |
Counts the number of times a disk read could not be satisfied from read-ahead buffers, and had to block. Indicates short streams or incorrect read ahead configuration. |
scylla_reactor_fstream_reads |
Counts reads from disk file streams. A high rate indicates high disk activity. Contrast with other fstream_read* counters to locate bottlenecks. |
scylla_tablets_count |
Tablet count |
