  • 1.  Imperva agent | DB discovery failure due to disk space threshold exceeded.

    Posted 20 days ago

    Hi All,

    Imperva agent activity log shows below error. Agent is installed on Microsoft Windows Server 2019 Datacenter Edition, 64-bit and MS SQL database. It was "Running with error" and eventually changed to "Running" without any interventions.

    Error messages: DB Discovery failure. ; DB discovery failure due to disk space threshold exceeded.

    Agent advance configuration setting sare as below:

    <agent-config>
    <quota>8000</quota>
    <files-dir>.</files-dir>
    <kernel_support_local_traffic_in_server_side>true</kernel_support_local_traffic_in_server_side>
    <external-traffic-monitoring-in-kern>true</external-traffic-monitoring-in-kern>
    <collect-Oracle-in-user-space>true</collect-Oracle-in-user-space>
    <keepalive-module-enabled>false</keepalive-module-enabled>
    <system-events-ipv6-listener-identified-enable>0</system-events-ipv6-listener-identified-enable>
    <mssql-advanced-monitoring>1</mssql-advanced-monitoring>
    <senders-amount>10</senders-amount>
    </agent-config>

    1. How to check predefined threshold for agent?
    2. Does this impact to DB monitoring/audit logs?
    3. What actions are required further?

    TIA.

    Hi Anuja,

    Why are you using the Oracle userspace configuration on the Windows agent with MSSQL installed? Set the Advanced config lines to its default and monitor the agent after restarting it. For a detailed analysis of the issue, you can open a case.

    Hi Emirhan,

    Thanks for your response. The configuration settings are very old, will need a CR in order to modify it. I know for MSSQL system, we need not metion Oracle configuration. However don't believe that will throw disk related error.

    Hi Anuja,

    Whether the disk space allocation is done in accordance with the requirements mentioned in the documentation: https://docs-cybersec.thalesgroup.com/bundle/v15.0-agent-release-notes/page/59037.htm ?

    Yes, we have checked file system utilization for Imperva agent and found under threshold value.

    Imperva file system utilization is currently 54% and 8GB space is free.
