How can I monitor the status of redis server using PRTG?

Article Comments

Hi Yoyo,

Yes, Redis supports snmp monitoring.

Using PRTG's SNMP Custom Sensor and the OID's below should get you started.

.1.3.6.1.4.1.20267.400.1.1  (redisConnectedClnts)
.1.3.6.1.4.1.20267.400.1.2  (redisConnectedSlavs)
.1.3.6.1.4.1.20267.400.1.3  (redisUsedMemory)
.1.3.6.1.4.1.20267.400.1.4  (redisChangsSncLstSv)
.1.3.6.1.4.1.20267.400.1.5  (redisTotalConnectns)
.1.3.6.1.4.1.20267.400.1.6  (redisCommandsPrcssd)

Hi unfortunately i cant make it work :

Apples-iMac:~ Apple$ snmpwalk -v 2c -c 209ijvfwer0df92jd -O e 46.4.255.57 .1.3.6.1.4.1.20267.400

SNMPv2-SMI::enterprises.20267.400 = No Such Object available on this agent at this OID

Whats wrong ?

Hi! Same error here. We are using Redis Version 2.6.16

Any clues how to get this working?

Thanks in advance!

Hi,

The steps needed for Linux are:

  1. Make sure you have the snmpd running on the server where redis is
  2. Install the snmp-redis from here https://github.com/masterzen/redis-snmp (has perl dependencies)
  3. Put the REDIS-SERVER-MIB.txt to a proper location depending on your distro
  4. Start snmp-redis daemon
  5. Restart snmpd

You should be able to get the data now: # snmpbulkwalk -m 'REDIS-SERVER-MIB' -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.20267.400 REDIS-SERVER-MIB::redisConnectedClients.0 = Gauge32: 1 REDIS-SERVER-MIB::redisConnectedSlaves.0 = Gauge32: 0 REDIS-SERVER-MIB::redisUsedMemory.0 = Counter64: 41466936 Bytes REDIS-SERVER-MIB::redisChangesSinceLastSave.0 = Gauge32: 0 REDIS-SERVER-MIB::redisTotalConnections.0 = Counter64: 766351 REDIS-SERVER-MIB::redisCommandsProcessed.0 = Counter64: 8406408 REDIS-SERVER-MIB::redisCPUSys.0 = Counter32: 86891 REDIS-SERVER-MIB::redisCPUUsr.0 = Counter32: 17685 REDIS-SERVER-MIB::redisBlockedClients.0 = Gauge32: 0 REDIS-SERVER-MIB::redisEvictedKeys.0 = Counter64: 0 REDIS-SERVER-MIB::redisExpiredKeys.0 = Counter64: 75385 REDIS-SERVER-MIB::redisKeyspaceHits.0 = Counter64: 6683851 REDIS-SERVER-MIB::redisKeyspaceMisses.0 = Counter64: 574268 REDIS-SERVER-MIB::redisPubsubChannels.0 = Gauge32: 0 REDIS-SERVER-MIB::redisPubsubPatterns.0 = Gauge32: 0 REDIS-SERVER-MIB::redisUptime.0 = Gauge32: 8845840 Seconds REDIS-SERVER-MIB::redisUsedMemoryRss.0 = Wrong Type (should be Counter64): Gauge32: 20766720

You can use -O n switch to return raw OIDs: # snmpbulkwalk -m 'REDIS-SERVER-MIB' -v 2c -O n -c public 127.0.0.1 .1.3.6.1.4.1.20267.400 .1.3.6.1.4.1.20267.400.1.1.0 = Gauge32: 1 .1.3.6.1.4.1.20267.400.1.2.0 = Gauge32: 0 .1.3.6.1.4.1.20267.400.1.3.0 = Counter64: 41466936 Bytes .1.3.6.1.4.1.20267.400.1.4.0 = Gauge32: 0 .1.3.6.1.4.1.20267.400.1.5.0 = Counter64: 766351 .1.3.6.1.4.1.20267.400.1.6.0 = Counter64: 8406408 .1.3.6.1.4.1.20267.400.1.7.0 = Counter32: 86891 .1.3.6.1.4.1.20267.400.1.8.0 = Counter32: 17685 .1.3.6.1.4.1.20267.400.1.9.0 = Gauge32: 0 .1.3.6.1.4.1.20267.400.1.10.0 = Counter64: 0 .1.3.6.1.4.1.20267.400.1.11.0 = Counter64: 75385 .1.3.6.1.4.1.20267.400.1.12.0 = Counter64: 6683851 .1.3.6.1.4.1.20267.400.1.13.0 = Counter64: 574268 .1.3.6.1.4.1.20267.400.1.14.0 = Gauge32: 0 .1.3.6.1.4.1.20267.400.1.15.0 = Gauge32: 0 .1.3.6.1.4.1.20267.400.1.16.0 = Gauge32: 8845840 Seconds .1.3.6.1.4.1.20267.400.1.17.0 = Wrong Type (should be Counter64): Gauge32: 20766720

Last but not least - make sure that the PRTG can access the SNMP port on the redis machine, check you firewall settings.

Use the PRTG custom sensor with the OIDs provided to get the data you want.

Good luck!

Old post I know but if you wanted to use PRTGs library just add this as a .oidlib to your snmplibs folder.

For people that are reading this thread. In the mean while someone made a custom sensor that can be used, much easier too:

Also it doesn't depend on the redis-snmp which doesn't seem to be maintained anymore (source is 6 years old).

Hello GuiltyNL,

Many thanks for your reply and for sharing the custom sensor!

Hello there,
thank you for your KB-Post.

There are basically two approaches to monitor Redis using PRTG:

Using SNMP

While it is possible to use SNMP, keep in mind however that as mentioned by GuiltyNL, redis-snmp is no longer maintained and over 6 years old. Alternatively, it's possible to use the custom-script alternative below.
