  • Add Hours to Ticket changed from 0.0 to 0.25
  • Status changed from new to closed
  • Resolution set to fixed
  • Total Hours changed from 0.0 to 0.25

Testing on the command line:

cd /etc/munin/plugins/
munin-run redis_127.0.0.1_6379 
  multigraph redis_commands
  commands.value 
  hits.value 
  misses.value 
  multigraph redis_dbs
  expires.value

The reason for this was that a BOA upgrade had changed the Redis password, so it needed to be copied from /etc/redis/redis.conf to /etc/munin/plugin-conf.d/munin-node and munin-node needed restarting.

I have updated wiki:PuffinServer#Muninconfigchanges with this info.

After having done that:

munin-run redis_127.0.0.1_6379 
  multigraph redis_clients
  clients.value 2
  multigraph redis_blocked_clients
  blocked.value 0
  multigraph redis_memory
  memory.value 191168560
  multigraph redis_fragmentation
  frag.value 1.11
  multigraph redis_total_connections
  connections.value 44314
  multigraph redis_expired_keys
  expired.value 19394
  multigraph redis_evicted_keys
  evicted.value 0
  multigraph redis_pubsub_channels
  channels.value 0
  multigraph redis_commands
  commands.value 1338388
  hits.value 832242
  misses.value 133973
  multigraph redis_dbs
  db0keys.value 38433
  db0expires.value 33340

So the graphs should start to appear here in a while:
