To successfully connect the Endpoint Operations agent to the vRealize Operations cluster, add the allowedRequestAttributesPattern=".*" entry to /usr/lib/vmware-vcops/tomcat-enterprise/conf/server.xml on all nodes in the cluster.

1. Log into the Primary node as root via SSH or Console, pressing ALT+F1 in a Console to log in.
2. Back up the server.xml file:

cp /usr/lib/vmware-vcops/tomcat-enterprise/conf/server.xml /tmp/server.xml

3. Open /usr/lib/vmware-vcops/tomcat-enterprise/conf/server.xml in a text editor.
4. Add allowedRequestAttributesPattern=".*" at the end of the <Connector port="${jk.port}" block.

Example:

....
<Connector port="${jk.port}"
           address="127.0.0.1"
           protocol="AJP/1.3"
           maxPostSize="-1"
           maxSavePostSize="-1"
           packetSize="65536"
           redirectPort="${bio-ssl.https.port}"
           secretRequired="false"
           URIEncoding="UTF-8"
           allowedRequestAttributesPattern=".*"/>
...

5. Save and close the file.
6. Run the following command to restart the API service:

/usr/bin/systemctl restart api

7. Repeat steps 1-6 on all nodes in the cluster, including remote collectors.
