Accounting file STM test configuration
In 5620 SAM Release 7.0 R4, the concept of accounting file collection of STM test
results was introduced. This feature requires 7750 and 7450 network elements that are
version 7.0 R4 and above. To take advantage of accounting file STM test execution, the
test policy must be configured to be NE schedulable with “Accounting file” selected. This
will produce STM tests that will be executed on the network element, while the test
results will be returned to 5620 SAM by way of an accounting file in a similar way to
accounting Statistics.
5620 SAM supports the use of logToFile for file accounting STM results. When using this
method only for results, the number of tests that can be executed per 10 minute interval is
increased. Refer to
Table 6-15, “Maximum number of STM elemental test results”
for specific scaling limits. The logToFile method for file accounting STM results
supports a maximum of two JMS clients.
Examples of STM test configuration
The following examples describe the configuration of STM tests on different network
configurations.
Example 1
Assume there is a network with 400 LSPs and that the objective is to perform LSP pings
on each LSP as frequently as possible. The following steps are to be followed:
1. Create 4 test suites each containing 100 elemental LSP ping tests
2. One at a time, execute each test suite and record the time each one took to complete.
Assume that the longest time for executing one of the test suites is 5 minutes.
3. Create a schedule that is ongoing and has a frequency of 10 minutes. This doubles the
time taken for the longest test suite and ensures that the test will complete before it is
executed again. Assign this schedule to the 4 test suites.
4. Monitor the test suite results to ensure that they are completing. If the tests are not
completing (for example getting marked as “skipped”), then increase the frequency
time value of the schedule.
5. In the above case, there are 200 elemental tests configured to be executed each 10
minutes.
Example 2
Assume there are eight test suites (T1, T2, T3, T4, T5, T6, T7 and T8), each containing 50
elemental tests. Assume the test suites individually take 5 minutes to run. Also, assume
the objective is to schedule them so that the guideline of having less than 200
concurrently running elemental tests is respected.
