Service Instance Metrics
This page describes the metrics used to monitor state of an a9s Redis®*. Service Instance. For further information on how to monitor an a9s Service Instance, see the Set up Monitoring section of the Application Developer's documentation.
Metrics
These are all metrics provided by a9s Redis®.
| Metric Id | Type | Description |
|---|---|---|
blocked_clients | Integer | Number of clients pending on a blocking call (BLPOP, BRPOP, BRPOPLPUSH, BLMOVE, BZPOPMIN, BZPOPMAX). documentation |
connected_clients | Integer | Number of client connections (excluding connections from replicas). documentation |
evicted_keys | Integer | Number of evicted keys due to maxmemory limit. documentation |
expired_keys | Integer | Total number of key expiration events. documentation |
instantaneous_ops_per_sec | Integer | Number of commands processed per second. documentation |
keyspace_hits | Integer | Number of successful lookup of keys in the main dictionary. documentation |
keyspace_misses | Integer | Number of failed lookup of keys in the main dictionary. documentation |
mem_fragmentation_ratio | Float | Ratio between used_memory_rss and used_memory. Note that this doesn't only includes fragmentation, but also other process overheads (see the allocator_* metrics), and also overheads like code, shared libraries, stack, etc. documentation |
rejected_connections | Integer | Number of connections rejected because of maxclients limit. documentation |
total_commands_processed | Integer | Total number of commands processed by the server. documentation |
total_connections_received | Integer | Total number of connections accepted by the server. documentation |
used_memory | Integer | Total number of bytes allocated by Redis® using its allocator (either standard libc, jemalloc, or an alternative allocator such as tcmalloc) documentation |
used_memory_lua | Integer | Number of bytes used by the Lua engine. documentation |
used_memory_peak | Integer | Peak memory consumed by Redis® (in bytes). documentation |
used_memory_rss | Integer | Number of bytes that Redis® allocated as seen by the operating system (a.k.a resident set size). documentation |
