You can use the Wowza Streaming Engine™ media server software REST API to view current and historical statistics about applications, incoming streams, and the server itself.
Notes:
- Wowza Streaming Engine 4.3.0 or later is required.
- PHP examples for the tasks in this article are available in the tests folder of the PHP REST Library for Wowza Streaming Engine on GitHub.
- Reference documentation for the Wowza Streaming Engine REST API is available by using Swagger, which you can download and install locally. See Access reference documentation for the Wowza Streaming Engine REST API.

Get current statistics for an application
View current statistics for an application (live in this example), including total connections, the number and rate of bytes entering and leaving the server, and the number of connections per protocol:
curl -X --header 'Accept:application/json; charset=utf-8' --header 'Content-Type:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/monitoring/current
The command should return a response that looks something like this (if the application is running, you should see real values, not zeros):
{
"serverName": "_defaultServer_",
"uptime": 0,
"bytesIn": 0,
"bytesOut": 0,
"bytesInRate": 0,
"bytesOutRate": 0,
"totalConnections": 0,
"connectionCount": {
"WEBM": 0,
"DVRCHUNKS": 0,
"RTMP": 0,
"MPEGDASH": 0,
"CUPERTINO": 0,
"SANJOSE": 0,
"SMOOTH": 0,
"RTP": 0
}
}
Get current statistics for an incoming stream
View current statistics for an incoming stream (myStream in this example):
curl -X GET --header 'Accept:application/json; charset=utf-8' --header 'Content-Type:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/instances/_definst_/incomingstreams/myStream/monitoring/current
The command should return a response that looks something like this (if the application is running, you should see real values, not zeros):
{
"serverName": "_defaultServer_",
"uptime": 0,
"bytesIn": 0,
"bytesOut": 0,
"bytesInRate": 0,
"bytesOutRate": 0,
"totalConnections": 0,
"connectionCount": {
"RTMP": 0,
"MPEGDASH": 0,
"CUPERTINO": 0,
"SANJOSE": 0,
"SMOOTH": 0,
"RTP": 0
},
"applicationInstance": "_definst_",
"name": "myStream"
}
Get historical statistics for an application
View historical details for an application (live in this example):
curl -X GET --header 'Accept:application/json; charset=utf-8' --header 'Content-Type:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/monitoring/historic
The command should return an entries object with actual, average, minimum, and maximum arrays of data for every date and time (dateTime) the application ran. The response should look something like this (but with real values, not zeros):
{
"serverName": "_defaultServer_",
"entries": {
"actual": [],
"average": [{
"dateTime": "2017-04-05T18:00:00",
"data": [
0,
0,
0,
0,
0,
0,
0,
0,
0,
0
]
}],
"min": [{
"dateTime": "2017-04-05T18:00:00",
"data": [...]
}],
"max": [{
"dateTime": "2017-04-05T18:00:00",
"data": [...]
}]
}
}
The dateTime is the UTC date and time that the server started. The values in each data array are, in descending order:
"data": [
bandwidth_inbound,
bandwidth_outbound,
rtmp,
rtsp,
hds,
hls,
smooth,
webrtc,
webm,
dash
]
Optionally, you can also include start and end time parameters in your query to return historical statistics only for that time range. Specify the start and end times in the format start=yyyy-mm-ddThh:mm:ss. For example, 2015-11-01T15:00:00. The following example query uses the start and end parameters:
curl -X GET --header 'Accept:application/json; charset=utf-8' --header 'Content-Type:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/monitoring/historic?start=2015-11-01T15:00:00&end=2015-11-01T15:01:00"
Get historical statistics for a server
View historical statistics for a server (_defaultServer in this example), including CPU, memory, and heap memory usage as well as connections to the server:
curl -X GET --header 'Accept:application/json; charset=utf-8' --header 'Content-Type:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/monitoring/historic
The command should return an entries object that shows the actual, average, minimum, and maximum values for every date and time (dateTime) the server ran. The response should look something like this :
{
"serverName": "_defaultServer_",
"entries": {
"actual": [],
"average": [{
"dateTime": "2017-04-05T18:00:00",
"data": [
0,
0,
0,
54
]
}],
"min": [{
"dateTime": "2017-04-05T18:00:00",
"data": [...]
}],
"max": [{
"dateTime": "2017-04-05T18:00:00",
"data": [...]
}]
}
}
The dateTime is the UTC date and time that the server started. The values in each data array are, in descending order:
"data": [
Bandwidth usage coming into the media server in kilobytes/second,
Bandwidth usage going out of the media server in kilobytes/second,
Java Heap memory usage in megabytes,
Total connection count (in AND out of the media server)
]
Optionally, you can also include start and end time parameters in your query to return historical statistics only for that time range. Specify the start and end times in the format start=yyyy-mm-ddThh:mm:ss. For example, 2015-11-01T15:00:00. The following example query uses the start and end parameters:
curl -X GET --header 'Accept:application/json; charset=utf-8' --header 'Content-Type:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/monitoring/historic?start=2015-11-01T15:00:00&end=2015-11-01T15:01:00"
