8.2 Configuring Message Buffering

Agent Manager uses persistent storage to protect against data loss, storing data locally on the agent level. Windows agents temporarily store data on the agent computer to safeguard against communication interruptions between the agent and the monitoring central computer. If a communication failure occurs, the agent stores any collected event or log data until the agent can re-establish a connection with the central computer and then sends all collected data.

Agent Manager categorizes pending agent messages as normal priority, invalid, or high priority, with buffer disk space allocated for messages of each category. The following table lists the default buffer sizes for each message category:

Message Category Name

Default Buffer Size (in KB)

Normal Priority

1000000

Invalid

10000

Using the Agent Manager Console, you can configure temporary storage settings globally, for all agents, or for specific agents in a configuration group. You can increase or decrease the default message buffer sizes, as necessary.

A Windows agent that cannot communicate with a central computer stores data until one of the following events occurs:

  • The agent can send the data.

  • The stored data grow to the size of the configured message buffering settings.

  • The stored data grow to fill the hard disk of the agent computer.

After the agent reaches either the agent’s message buffering settings or the hard disk space limit of the computer, the agent stops processing collected data. Event data remains in the native event logs until the agent can begin processing again.

To configure temporary storage settings:

  1. Log on to the Agent Manager Console computer using an account that is a member of the OnePointOp ConfgAdms group.

  2. Start the Agent Manager Console in the NetIQ Sentinel Agent Manager program group.
