Redis
Retrieve data and metrics from a Redis instance to effectively monitor the performance of the Redis server.
Prerequisites
Before using this integration, ensure that the Middleware Host agent has been successfully installed on your machine.
Setup
Follow these steps to set up the Redis integration:
- Create a YAML file on your system containing the database collection details, as shown below:
Ex. /home/ubuntu/redis-creds.yaml
redis:
endpoint: localhost:7379
password: redis
-
password
: if your Redis server requires authentication.-
transport
(default = tcp
): Type of network, to access the server. Options: tcp
and Unix
.-
tls
:-
insecure
(default = true): To switch client transport security for the connection.-
ca_file
: Path to the CA certificate file.-
cert_file
: Path to the TLS certificate file.-
key_file
: Path to the TLS key file./var/log
directory. This is because, the Docker agent might not support dynamic volume binding.- In the Middleware Store, enable the Redis Integration, select a host, and provide the YAML file path created in step 1.

Visualize Analytics
Redis analytics can be visualized in two ways:
1. Middleware’s Default Redis Dashboard
After setting up the Redis Integration, you will gain access to various analytics in the default Redis Dashboard.

2. Create your own dashboard
You have the flexibility to create your own dashboard from scratch.
When adding a new widget to an existing dashboard, you will find a list of available Redis metrics under the “redis” data source.
These metrics can be visualized using various widget types, such as Timeseries, Bar Chart, Pie Chart, and more.

Metrics collected
Below is a list of Redis metrics that this integration will collect:
Metric | Description |
---|---|
redis.maxmemory | The value of the maxmemory configuration directive |
redis.role | Redis node’s role |
redis.cmd.calls | Total number of calls for a command |
redis.cmd.usec | Total time for all executions of this command |
redis.uptime | Number of seconds since Redis server start |
redis.cpu.time | System CPU consumed by the Redis server in seconds since server start |
redis.clients.connected | Number of client connections (excluding connections from replicas) |
redis.clients.max_input_buffer | Biggest input buffer among current client connections |
redis.clients.max_output_buffer | Longest output list among current client connections |
redis.clients.blocked | Number of clients pending on a blocking call |
redis.keys.expired | Total number of key expiration events |
redis.keys.evicted | Number of evicted keys due to maxmemory limit |
redis.connections.received | Total number of connections accepted by the server |
redis.connections.rejected | Number of connections rejected because of maxclients limit |
redis.memory.used | Total number of bytes allocated by Redis using its allocator |
redis.memory.peak | Peak memory consumed by Redis (in bytes) |
redis.memory.rss | Number of bytes that Redis allocated as seen by the operating system |
redis.memory.lua | Number of bytes used by the Lua engine |
redis.memory.fragmentation_ratio | Ratio between used_memory_rss and used_memory |
redis.rdb.changes_since_last_save | Number of changes since the last dump |
redis.commands | Number of commands processed per second |
redis.commands.processed | Total number of commands processed by the server |
redis.net.input | The total number of bytes read from the network |
redis.net.output | The total number of bytes written to the network |
redis.keyspace.hits | Number of successful lookup of keys in the main dictionary |
redis.keyspace.misses | Number of failed lookup of keys in the main dictionary |
redis.latest_fork | Duration of the latest fork operation in microseconds |
redis.slaves.connected | Number of connected replicas |
redis.replication.backlog_first_byte_offset | The master offset of the replication backlog buffer |
redis.replication.offset | The server’s current replication offset |
redis.db.keys | Number of keyspace keys |
redis.db.expires | Number of keyspace keys with an expiration |
redis.db.avg_ttl | Average keyspace keys TTL(Time to live) |
