Redis Monitor

The Redis monitor in updu speaks the RESP (REdis Serialization Protocol) directly. It authenticates and runs a PING command against the server to ensure the in-memory data store is responsive and actively processing commands.

Configuration Options

When setting up a Redis monitor, you can configure the following options:

Basic Settings

• Name: A descriptive name for your monitor.
• Group: Optional group assignment for organizing monitors.
• Interval (seconds): How frequently updu should perform the check.
• Timeout (seconds): The maximum time updu will wait for an authenticated connection before considering the check failed.

Redis Specific Settings

• Hostname: The IP address or domain name of your Redis instance (e.g., cache.example.com).
• Port: The port your Redis instance is running on (standard is 6379).
• Auth Password: (Optional) Provide the password if your instance requires the AUTH command to accept connections.
• Database Index: (Optional) The integer database index updu will run SELECT against to confirm availability. Defaults to 0.

Example Use Cases

• Background Job Queues: Be alerted when the cache server holding in-flight Celery or Sidekiq jobs goes offline, preventing application hangs before they happen.
