HBR

Through the Portal, you can review the current status of the HBR machine.

About this task

  • Health-Based Routing enables load balancing between multiple Canisters in a Discover environment. See "Health-Based Routing (HBR) Session Agent" in the Unica Discover Configuration Manual.

Procedure

  1. In the Portal menu, select Discover > System Status > Health Based Routing.
  2. In the General section, review the Health message.
    • If all Canisters are reporting good health, the message should read something like the following:
      
      4 out of 4 Canisters Healthy and Available
      
  3. To identify if hits are being spooled, review the value for Current Spooled Hits.
    • This value must be assessed based on the current and expected traffic volume. You should divide this value by the number of hits per second. This value can be retrieved from the Pipeline Status tab in Manage Services. See Manage Services Pipeline Status Tab.
  4. Below the General report are two graphs indicating the percentage of healthy Canisters out of the total available and the percentage of traffic that is being properly passed to a Canister for evaluation.
  5. At the bottom of the report, you can review the status information for individual Canisters configured to receive hits from HBR.
    1. For a health Canister, the Health State message should be the following:
      
      Healthy
      
    2. Other status messages typically include a Reason, which may be explored through other System Status reports, as described in the following sections. See Some hits are arriving into the Canister.
    3. If a Canister is overburdened and unable to keep up, you should verify that the Routing value does not indicate that the Canister is receiving too high of a percentage of traffic from HBR.
  6. To refresh the report, click Refresh in the left navigation panel.

About this task

  • There is no data in the HBR report, then the HBR machine may be down.
    • In the Portal Management page, you should ping the machine hosting HBR. See Discover Servers.
  • Some Canisters are reporting that they are down or in an unhealthy state, you should investigate each one using the Canister status report. See Canister Health.
  • All Canisters are down, then HBR is unable to communicate with them.
    • In the Portal Management page, you can verify the configuration and availability of each Processing Server. See Discover Servers.
    • The problem may be an error in how the Canister configurations for HBR. See "Health-Based Routing (HBR) Session Agent" in the Unica Discover Configuration Manual.
