Creating an SLA

How to

  1. Click the Central tab > SLAs and then the new button on the top.
  2. Name the SLA and enter a Location.
  3. Appiles To: Choose whether the SLA rules you create will apply to a Collection.
  4. Collection: Pick a rule and enter values to specify the ranges. The start of each range is inclusive.
    • Minimum Completions Per Second: Number of completions of the Transaction/Group/Page divided by the number of seconds in the test.
    • Maximum Nth Percentile Duration: The Nth Percentile for all collections where N is specified by the user (eg. 90th). Only successfully completed collections are included. (If the Maximum Nth Percentile Duration is greater than the threshold, then the rule is in violation.)
    • Maximum Error Percentage: Number of Transaction/Group/Page errors divided by the number that started.
    • Minimum Duration:The collection with the shortest effective duration. Only successfully completed collections are included. (If the Minimum Duration is less than the threshold, then the rule is in violation.)
    • Maximum Duration: The 90th (default) percentile duration of the Transaction/Group/Page.
    • Average Duration: The total effective duration for all collections (transactions, pages, groups) divided by the total number of collections which started. Only successfully completed collections are included. (If the Average Duration is greater than the threshold, then the rule is in violation.)
    • Average HTML Doc Duration:The average duration of all the base HTML pages for all Page type collections. Only successfully completed pages are included. (If the Average HTML Doc Duration is greater than the threshold, then the rule is in violation.)
  5. Composition: Pick a rule and enter values to specify the ranges. The start of each range is inclusive.
    • Average Response Time: The average (mean) response time for all messages in the test. Only messages which received a response are included.
    • Throughput (bits Per Second): The total number of bits, sent and received, divided by the number of seconds in the test.
    • Throughput Sent (bits Per Second):The total number of bits sent divided by the number of seconds of the test.
    • Throughput Received (bits Per Second): The total number of bits received divided by the number of seconds of the test.
    • Minimum Message Completions Per Second:The total number of messages/actions that received a response, divided by the number of seconds of the test
    • Maximum Message Error Percentage:The total number of message/action errors divided by the number of message/action send attempts.
    Note: SLA rules are evaluated at the end of the test and apply to the entire test. The rule is applied to the aggregated metrics for a specific Transaction/Group/Page across all virtual users.
  6. Open the Composition Editor (by clicking on Compositions > New Test Composition) for the Composition for which SLAs will be applied. You should already have a clip ready in the Composition Editor.Caution: Save your Composition before continuing.
  7. In the lower panel, click Properties > Composition > SLA
  8. Click to add a new rule and browse for an SLA. For SLA rules that apply to collections, click the Choose Collections button to browse for a transaction path.
  9. Alternatively, wild cards can be applied to multiple transactions. Below, the path CommonBrowsingClip/ProductViewingGroup/Page* also applies to the following.

What you should see

  • CommonBrowsingClip/ProductViewingGroup/PageSportsEquipment
  • CommonBrowsingClip/ProductViewingGroup/PageClothing
Note: Wildcards must be entered manually and must be completed with an asterik.
