Watchdog: Redis

The check opens a TCP connection to the Redis server, sends PING and expects the reply +PONG.

Property	Value
Type identifier	`redis`
Runner	Dashboard or Agent
Target in the email	`Host:Port`

Fields

Field	Key	Default	Meaning
Host	`host`		Required. Host name or IP address of the Redis server
Port	`port`	`6379`	Redis port, 1 to 65535
Timeout (seconds)	`timeout`	`3`	Time limit for connection and reply, clamped to 1 to 60 seconds

Behaviour

Situation	Status	Message
Reply `+PONG`	`OK`	`<host>:<port> responded with PONG`
Connection fails	`FAIL`	`Connection to <host>:<port> failed: <reason>`
No reply	`FAIL`	`No response received from <host>:<port>`
Any other reply	`FAIL`	`Unexpected response from <host>:<port>: <reply>`
Invalid port	`UNKNOWN`	`Invalid port configured`
No host	`UNKNOWN`	`No host configured`

The check sends no AUTH and speaks no TLS. A password-protected Redis server answers PING with an error (for example -NOAUTH ...), and the check then reports FAIL with Unexpected response.
