Web agent relay configuration
Relays can be configured to support web agents exclusively.
You must upgrade relays for agents with web communication enabled and associate with the relay
from the UI. However, a successful agent communication does not require any configuration. The
following web communication parameters are defined in the
relayInstallDir/conf/agentrelay.properties file:
agentcomm.enabled=true
agentcomm.server.uri=random:(wss://ucd1.example.org:7919,wss://ucd2.example.org:7919)Agent relay limits
The maximum number of agents that can be assigned to a relay is limited in each of the releases.
See to the following table to check the number of agents that are allowed for a relay for your
installedIBM® UrbanCode® Deploy version.
| Version | Relay mode | Agent type | Limit with default proxy |
|---|---|---|---|
| 7.0.4.0 to 7.0.5.0 | Web mode | Web Agents | 1K |
| 7.0.5.0 or later | Web mode | Web Agents | 10K |
In Linux, use the following utilities to reach the design limit of 10K concurrent agents:
- sysctl:
fs.file-max >= 40000 - ulimit:
nofile >= 40000 - sysctl:
net.ipv4.ip_local_port_range >= "10000 65000"
