5.5.5 Fastline parameters

This section describes the parameters for the Fastline plug-in.

Each parameter is prefixed with TRACE.FastlineTrace, for example:

TRACE.FastlineTrace.config

Note:

The trace-start-time and trace-end-time parameters apply to every counter. You can also specify a StartTime and EndTime for individual counters in the counter configuration file. If so, the time period in which trace occurs for a counter is the overlap between the two periods specified.

Table 5-7 Fastline parameters

Name Type Default value Allowed values Description
apc-capture string "fastmodels.apc" ""

Name of the APC capture directory that Fastline generates.

Optional.

config string "" ""

The system configuration file. This JSON file defines which cluster configuration file to use for each cluster.

Mandatory.

counters-config-file string "" ""

The counter configuration file. This JSON file maps MTI trace sources to Streamline counters and sets the parameters for the capture.

Optional. If omitted, no counters are generated in the capture.

output-directory string "." ""

Directory for the APC capture that Fastline generates.

Optional. If omitted, the APC is created in the current directory.

time-base int 0x0 0x0 - 0x1 Selects whether time stamps are based on simulated time or host time:
0
This value is the default. Time stamps are based on simulated time and therefore are deterministic. This is useful when the trace-start-time or trace-end-time parameters are used, or if a repeatable time logging result is required.
1
Time stamps are based on host time, and therefore are non-deterministic. This can be useful for performance benchmarking, but is generally not recommended.
trace-start-time int 0x0 0x0 - -0x1

The simulated time in nanoseconds at which trace is enabled for Fastline.

Optional. If omitted, the default is zero.

trace-end-time int -0x1 0x0 - -0x1

The simulated time in nanoseconds at which trace is disabled for Fastline.

Optional. If omitted, the default is 0xffffffffffffffff.
