Function Detail (for Supporting System Operation and Management)

Monitoring Functions#

hcpd is available to run in foreground. All commands can output debug information (logs in debug level) if you change the level. And you can configure timeouts to detect transport disconnection or idling among operations on the server.

Please be careful of unexpected timeouts from changing the log level to debug since producing many logs makes delays of processing on file transfer on some environment, e.g. computers behind NAT.

* On Unix platforms, Archaea tools also output logs from syslog subject to its system configuration.

* As other forms of recording running results, it save a running result of a command to a specific file (.hcp.out on Linux and _hcp.out on Windows). This file is overwritten when each command runs. So the file dose not hold records before the current run.

Archaea tools provides the following logging management functions for each type of logs.

Destination to Output Logs
You can specify a destination to output logs by changing configuration files of a server and client or using command options.
If you use the command options, you can specify the destination each command execution. The options are 'log-file' and 'stat-log-file' except for hsync. For hsync, 'hcp-log-file' and 'hcp-stat-log-file' are provided as identical options for them.
Log Level
You can set a log level to logs Archaea tools produces. It can be chosen from EMERG, ALERT, CRIT, ERR, WARNING, INFO and DEBUG that are subject to the Severity of Syslog.
Log Rotation
For each log, you can specify log rotation subject to threshold of a file size or date and time.
