ScyllaDB Enterprise 2024.2 Dashboards are available as part of the latest Scylla Monitoring Stack.
The following metrics are new in ScyllaDB Enterprise 2024.2 compared to 2024.1:
Metric |
Description |
|---|---|
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_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_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_reads |
Counts reads from disk file streams. A high rate indicates high disk activity. Contrast with other fstream_read* counters to locate bottlenecks. |
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_rpc_client_count |
Total number of clients. |
scylla_rpc_client_exception_received |
Total number of exceptional responses received. |
scylla_rpc_client_pending |
Number of queued outbound messages. |
scylla_rpc_client_replied |
Total number of responses received. |
scylla_rpc_client_sent_messages |
Total number of messages sent. |
scylla_rpc_client_timeout |
Total number of timeout responses. |
scylla_rpc_client_wait_reply |
Number of replies awaited. |
scylla_storage_proxy_coordinator_mv_flow_control_delay_total |
Total delay (in microseconds) added for MV flow control to delay the response sent to finished writes. Divide it by throttled_base_writes_total to find the average delay. |
scylla_storage_proxy_coordinator_throttled_base_writes_total |
Number of throttled base replica write requests, a throttled write is one whose response was delayed; see mv_flow_control_delay_total. |
