Cluster Health

These instructions assume you are running as root. All services MUST be working as indicated in order to have a properly running Kazoo platform.

FreeSWITCH

Is FreeSWITCH running?

  service freeswitch status
 
  freeswitch(pid:xxxx): up

If not then:

service freeswitch start   Is FreeSWITCH Connected?

FreeSWITCH must be connected to the rest of the platform. You can check this from within FreeSWITCH itself. Enter the

FreeSWITCH CLI and check for erlang listener(s). You should have at least one:

  cli -x 

  erlang listeners

You should see at least one of your other servers listed. If you don’t, or there are no listeners, then FreeSWITCH is running by ecallmgr is not connected to it.  

ECallMgr

Is ECallMgr Running?

ECallMgr connects the Kazoo platform with all FreeSWITCH servers. It is the primary link between FreeSWITCH and the rest of the platform.   `service ecallmgr status

[freeswitch@fs001.yourserver.com,

freeswitch@fs002.yourserver.com]`

This command should return a list of FreeSWITCH nodes which ECallMgr is connected to, in JSON format.   If it does not, try restarting ECallMgr:

service ecallmgr restart

Check RabbitMQ status

RabbitMQ provides the glue between FreeSWITCH and the Kazoo Applications: service rabbitmq-server status

That command should return something like:  ``` #Status of node rabbit@mydomain.com…

[{pid,2049 },   { running_applications,[{rabbit,

RabbitMQ, 2.7.0 },                          {os_mon, CPO  CXC 138 46, 2.2.6},                          {sasl, SASL  CXC 138 11, 2.1.9.4},                          {mnesia, MNESIA  CXC 138 12, 4.4.19},                          {stdlib,ERTS  CXC 138 10, 1.17.4},                          {kernel,ERTS  CXC 138 10,2.14.4}]},   {os,{unix,linux}},   {erlang_version,

Erlang R14B03 (erts-5.8.4) [source] [64-bit] [smp:4:4] [rq:4] [async-threads:30] [kernel-poll:true]\n},   {memory,[{total, 26165880},            {processes, 10842712},            {processes_used, 10828488},            {system, 15323168},            {atom, 1122017},            {atom_used, 1116886},            {binary, 115952},            {code, 11271185},            {ets, 865008}]},   {vm_memory_high_watermark,0.3999999997516473},   {vm_memory_limit, 322122547}]`

…done.   #If not then:   # service rabbitmq-server restart  ```

Kazoo Applications

  # service whapps status   Should give you something like: Searching for running WhApps on whistle_apps@mydomain.com

[cdr,sysconf,conference,registrar,hangups,media_mgr,crossbar,callflow,stepswitch]
 ```
If it does not, try restarting it. 

`service whapps restart`
 
Some of these are optional and some are mandatory. I believe **Crossbar** is necessary for **Winkstart** to work. If **Crossbar** is not there you can try running 

`whapps_maintenance:refresh().`

## HAProxy
 
`# service haproxy status`

haproxy (pid  xxxx) is running...and if not
 
`# service haproxy restart`
 

## Check BigCouch

Assuming localhost
 
  `# curl localhost: 5984

  { couchdb: Welcome, version: 1.1.1, bigcouch: 0.4.0}`
 
if not then check and double check your haproxy config and status and try:
 
`# service bigcouch restart`
