Risks, Limitations & Assumptions
- The integration can manage critical/recovery failure alerts for the following two scenarios when the user activates App Failure Notifications in the settings:
- Connectivity Exception
- Authentication Exception
- Oracle Cluster will send any duplicate/repeat failure alert notification for every 6 hours.
- Metrics can be used to monitor Oracle resources and can generate alerts based on the threshold values.
- We have provided the provision to give Cluster Ip Address OR HostName in configuration, but hostName provision will work only if the host name resolution works.
- Oracle Cluster supports only Classic Gateway and NextGen Gateway. Not supported with Cluster Gateway.
- No support of showing activity logs.
- The Template Applied Time will only be displayed if the collector profile (Classic and NextGen Gateway) is version 18.1.0 or higher.
- Component level thresholds can be configured on each resource level.
- Latest snapshot metric support from Gateway 14.0.0.
- Currently, SSH authentication is supported using credentials (username and password). However, SSH key-based authentication is not supported.
Troubleshooting
Before troubleshooting, ensure all prerequisites prerequisites are met.
If Oracle Cluster integrations fail to discover or monitor, troubleshoot using the following steps:
- Check if any alerts have been generation on the cluster or in vprobe.
- If there is an error or alert related to the end device connectivity or authentication, try checking the reachability of the end device from the gateway with the following commands:
- to ping the scan hostname provided in the configuration:
{ping <scan name>}
- to try telnet:
{telnet <scan name> <Port>}
- to try ssh to the end device:
{ssh <username>@<node IP Address>}
- to connect to the gcli:
{gcli}
{db oracledb <scan_name> <username> <password> <db_port> <db_name>:servicename 15000 10000 insecure Yes "SELECT INST_ID, INSTANCE_NUMBER, INSTANCE_NAME, HOST_NAME FROM gv$instance"}
- to try SSH to nodes:
{ssh <user name>@<node IPAddress>}
- to ping the scan hostname provided in the configuration:
