Circuitcheck_completed_bins, log_delay_bins, log_frustraction_limit, log_size_bins, log_statistics MTA options

From MsgServerDocWiki

Counters options (circuitcheck_completed_bins, log_delay_bins, log_frustraction_limit, log_size_bins, log_statistics)

The MTA has a number of options relating to its counters. The circuitcheck_completed_bins option relates to MTA circuit check counter binning. The log_delay_bins and log_size_bins options relate to MTA counters binning. See also the sndopr_priority MTA option, which controls the syslog facility and severity of, among other things, syslog notices generated if and when the MTA encounters trouble with its association counters.

circuitcheck_completed_bins (comma-separated list of up to eight integers)

The circuitcheck_completed_bins MTA option specifies the   bin divisions, in seconds, for MTA   circuit check counters. It takes as argument a list of up to eight integer  values.    The default values are 120, 300, 900, 1800,  3600, 7200, 14400, and 28800; i.e., two minutes, five minutes,  fifteen minutes, thirty minutes, one hour, two hours, four hours, and  eight hours, respectively. 

log_delay_bins (comma-separated list of up to five integers)

This option specifies the bin divisions for the MTA counters tracking numbers of messages delivered in the specified number of seconds. The defaults values are 60, 600, 6000, 60000, 600000.

log_frustration_limit (integer)

When attempting a counter update operation (whether an attempt to update channel counters or association counters), the MTA will try ten times before giving up on that particular update operation. Each MTA process keeps track of how many such update "frustrations" have occurred, that is, how many times the process has had to give up on updating the counters, and if that value exceeds the log_frustation_limit value, which by default is 100, then that process will no longer even attempt counter update operations.

log_size_bins (comma-separated list of up to five integers)

This option specifies the bin divisions for the MTA counters tracking numbers of messages of the specified number of (MTA) blocks (the size of an MTA block having deen defined via the block_size MTA option). The default values are 2, 10, 50, 100, 500.

log_statistics (0, 1, or 2)

Usage: RESTRICTED. (In PMDF V5.1 and earlier, log_statistics=0 told PMDF not to generate and maintain its counters; but as of PMDF V5.2, log_statistics=0 has no effect and is equivalent to log_statistics=1.) log_statistics=1 is the default and means to create counters normally. log_statistics=2 causes "strict" creation of counters; the MTA aborts if the counters cannot be created.
