Viewing target information

Each time the collector interacts with an SNMP agent, information about the interaction is recorded.

Procedure

  1. Click Collector Information from the Monitor tab.
  2. Select a collector from the list.
  3. Click the Targets tab. The Targets window displays the following information:
    Item Description
    Agent SNMP Version [immediate] Indicates the SNMP Version of the agent for the collector.
    Average SNMP Response Time (ms) [last hour] Indicates the average elapsed time between the sending of the first SNMP packet and its return. Time is not calculated on the exchanged packets during the MIB browse.
    CALC Errors (Nb) [last hour] Indicates the number of CALC errors that occurred in the last hour.
    CPU Load (Nb OIDs) [last hour] Indicates the estimated CPU load needed by the collector to handle all requests relating to this target. This measurement integrates the number of OIDs handled to solve the requests, the number of requests necessary, and the frequency of each interrogation.
    Discovery Received PDU (Nb) [last hour] Indicates the number of PDUs received as part of the discovery process in the last hour.
    Discovery Received PDU Max Size (bytes) [last hour] Indicates the maximum size of PDUs received as part of the discovery process in the last hour.
    Discovery Received PDU Total Size (bytes) [last hour] Indicates the total size of PDUs received as part of the discovery process in the last hour.
    Discovery Sent PDU (Nb) [last hour] Indicates the number of PDUs sent as part of the discovery process in the last hour.
    Discovery Sent PDU Max Size (bytes) [last hour] Indicates the maximum size of PDUs sent as part of the discovery process in the last hour.
    Discovery Sent PDU Total Size (bytes) [last hour] Indicates the total size of PDUs sent as part of the discovery process in the last hour.
    Expected Measures (Nb) [last hour] Indicates the number of measures expected in the last hour.
    Max SNMP Response Time (ms) [last hour] Indicates the maximum amount of time for an SNMP response that occurred in the last hour.
    OID Rate (Nb/s) [last hour] Indicates the OID rate that occurred in the last hour.
    Produced Measures (Nb) [last hour] Indicates the number of measures produced in the last hour.
    Received PDU (Nb) [last hour] Indicates the number of PDUs received in the last hour.
    Received PDU Max Size (bytes) [last hour] Indicates the maximum size of PDUs received in the last hour.
    Received PDU Total Size (bytes) [last hour] Indicates the total size of PDUs received in the last hour.
    SNMP Availability (%) [last hour] Indicates the reliability of the interaction with SNMP agents. A value of 0% can indicate a bad community name or that the timeout value is insufficient. A value more than 0% but less than 100% is often caused by timeouts during the SNMP interaction.
    SNMP Errors (Nb) [last hour] Indicates the total amount of errors in the SNMP protocol encountered during the interaction. An error cannot occur when the community name is correct and the timeout is correctly configured. An error signifies either an agent problem in responding to a packet or an error between the collector MIB and the MIB supported by the agent. Most often it indicates a problem with a formula.
    SNMP Requests (Nb) [cumul] Indicates the total number of executed requests on equipment since the start of the collector. You can identify the equipment with a high rate of requests.
    Sent PDU (Nb) [last hour] Indicates the number of PDUs sent in the last hour.
    Sent PDU Max Size (bytes) [last hour] Indicates the maximum size of PDUs sent in the last hour.
    Sent PDU Total Size (bytes) [last hour] Indicates the total size of PDUs sent in the last hour.
