dahdi_test — Test if the DAHDI timer provides timely response
dahdi_test [ -v ]
dahdi_test dahdi_test runs a timing test in a loop and prints the
result of each loop. The test is as follows:
It reads 8192 bytes from the DAHDI timer device (/dev/dahdi/pseudo).
This should take exactly 8000 ms . It uses calls to gettimeofday(2)
before and after that read to check that indeed exactly 8000ms have
Values of 100% and 99.99% Are normally considered a definite pass.
Values of 99.98% and 99.97% are probably OK as well.
Be more verbose: print one line per test.
Run for count times instead of running forever.
The device file used to access the DAHDI timer.
dahdi_tool(8), dahdi_cfg(8), asterisk(8). gettimeofday(2)
