To apply any configuration changes, backend server must be restarted.
Metrics storage DB connection setup
Influx BD connection setup
The following parameter in wcsoam.properties file should be set to allow to store metrics to Influx DB
| Code Block | ||
|---|---|---|
| ||
influxdb_enabled=true |
...
| Code Block | ||
|---|---|---|
| ||
influxdb_database=wcs_oam influxdb_user=root influxdb_password=root |
It is recommended to connect to By default, WCS OAM connects to Influx DB via UDP if WCS server is under high load, and incoming metrics traffic is big:
| Code Block | ||
|---|---|---|
| ||
influxdb_udp=true influxdb_udp_port=8089 |
...
In this case, metric values can be lost. To escape loss, metric values can be passed using HTTP POST query as follows
| Code Block | ||||
|---|---|---|---|---|
| ||||
POST /write?u=root&p=root&db=wcs_oam&rp=default&precision=n&consistency=one HTTP/1.1
3-5062030c-9def-49c2-a89e-639d664ab806 AUDIO_CODEC=102i,AUDIO_LOST=3795015i,AUDIO_RATE=137776i,AUDIO_SYNC=123432141899i,seq=26558i 1562263828767000000 |
Metrics writing can be switched to HTTP with the following parameter
| Code Block | ||
|---|---|---|
| ||
influxdb_udp=false |
Anyway, metric values are read from Influx DB using HTTP GET query as follows
| Code Block | ||||
|---|---|---|---|---|
| ||||
GET /query?u=root&p=root&db=wcs_oam&q=SELECT+*+FROM+%221-89dc5510-a198-11e9-a049-030fe6b5675c%22+order+by+time+desc+limit+10+offset+0 HTTP/1.1 |
Timescale DB connection setup
The following parameter in wcsoam.properties file should be set to allow to store metrics to Timescale DB
| Code Block | ||
|---|---|---|
| ||
metric_store=timescale |
DB URL and access parameters should be set for connection setup
| Code Block | ||
|---|---|---|
| ||
timescale.url=jdbc:postgresql://127.0.0.1:5432/wcsstat
timescale.username=wcsoam
timescale.password=wcsoam |
Connection tuning
Metric values batch size to write to DB can be set with the following parameter
| Code Block | ||
|---|---|---|
| ||
timescale_batch_size=1000 |
In this case metrics will be written to DB in batches of 1000 values.
Stream history and data acquisition settings DB connection setup
History storage support is enabled with the following parameter
...
By default, queue size is 3000 records.
SQL queries logging
If necessary, SQL queries logging can be enabled for debug purposes using the following parameters in wcsoam.properties file
| Code Block | ||
|---|---|---|
| ||
logging.level.org.hibernate.SQL=debug logging.level.org.hibernate.type.descriptor.sql=trace |
Note that metrics store to TimescaleDB will also be logged in this case.
WCS interaction setup
By default, backend server listens to WCS server connections for metrics acquisition on TCP port 7777. This port can be changed with the following parameter
...
Connection authentication key should be set with the following parameter
| Code Block | ||
|---|---|---|
| ||
secretsecurity_key=123456789 |
By default, authentication key is set to 123.
...
Backend server allows client connections using HTTPS and Secure Websocket. SSL is configi=ured configured with the following parameters
| Code Block | ||
|---|---|---|
| ||
server.ssl.key-store-type=JKS server.ssl.key-store=file:/usr/local/FlashphonerWebCallServerOAM/conf/wss.jks server.ssl.key-store-password=password server.ssl.key-alias=selfsigned |
Where:
- server.ssl.key-store-type - SSL certificate storage type, ; only JKS only is supported
- server.ssl.key-store - SSL certificate storage location
- server.ssl.key-store-password - SSL certificate storage password
- server.ssl.key-alias - domain name
