ups_mond(1M) ups_mond(1M) NAME
ups_mond - HP PowerTrust Uninterruptible Power System monitor daemon SYNOPSIS
configfile] DESCRIPTION
When it detects a loss of AC power for a period of time exceeding a configured limit, ensures file system integrity by shutting down HP-UX. To do this, uses the device special files specified in its configuration file by default) to monitor the state of each HP PowerTrust Unin- terruptible Power System (UPS) attached to the system. Use the option to specify a configuration file other than See ups_conf(4) for a description of the configuration file format. By default, is locked into memory (see plock(2)). That is, is not swappable. Although extreme caution is required, you can make swappable if all swap disks are powered by an uninterruptible power system (assured to have power when the primary power source fails). To make swappable, use the option. When is forced to shutdown the system, it executes the command with real-time priority (default behavior). can be configured to execute command with a timeshare (non-real-time) priority by using the option. is started by (see init(1M)) by means of an entry in the file (see inittab(4)). The entry uses the option to automatically restart if is terminated by the command (see kill(1)). This entry should follow the entry: so that is started after the system logging daemon It should also be run with real-time priority to assure its execution (see rtprio(1)). logs messages, and when appropriate invokes using the option, or For each configured UPS, can be instructed (in to log messages only, with- out taking or action. See MSG_ONLY in ups_conf(4). By default performs the and actions. Note that when the shutdown is performed, UPSs that have lost AC line voltage will be turned off once the shutdown_timeout_mins time has expired (see ups_conf(4)). By default the system will power on when the AC line voltage is restored. The kill_after_shutdown line can be added to to tell the UPS not to come back up when AC line voltage is restored (see ups_conf(4)). uses the message logging facility to log these occurrences (see syslog(3C)). Messages are written to the console if is unable to send them to Critical messages (see DIAGNOSTICS section) are also sent to the console. RETURN VALUE
returns the following values: zero(0) Successful Completion non-zero Error encountered. See ERRORS below. EXAMPLES
The entry in should be similar to this: DIAGNOSTICS
Messages resulting from normal operation: Messages resulting in exit of daemon: Messages for which might be run (depends on UPS configuration): Messages for which might be run (depends on UPS configuration): The above messages are followed by the following message: Messages that are only logged (no action is taken): Messages relating to Timer Controlled Power On and Off: ERRORS
returns the following error values: encountered an incorrect parameter. Insufficient privileges. must be started by a superuser. was interrupted (terminated) by or See signal(2) and kill(1). one(1) For all other error conditions. FILES

syslog(3C) syslog(3C) NAME
syslog(), openlog(), closelog(), setlogmask() - control system log SYNOPSIS
Remarks The ANSI C "" construct denotes a variable length argument list whose optional [or required] members are given in the associated comment DESCRIPTION
writes a message onto the system log maintained by (see syslogd(1M)). The message is tagged with priority. The message is similar to a printf(3S) format string except that is replaced by the error message associated with the current value of A trailing newline is added if needed. This message is read by and written to the system console, log files, selected users' terminals, or forwarded to on another host as appropriate. priority is encoded as the logical OR of a level and a facility. The level signifies the urgency of the message, and facil- ity signifies the subsystem generating the message. facility can be encoded explicitly in priority, or a default facility can be set with (see below). level is selected from an ordered list: A panic condition. This is normally broadcast to all users. A condition that should be corrected immediately, such as a corrupted system database. Critical conditions, such as hard device errors. Errors. Warning messages. Conditions that are not error conditions, but should possibly be handled specially. Informational messages. Messages that contain information normally of use only when debugging a program. does not log a message that does not have a level set. If cannot pass the message to it attempts to write the message on if the option is set (see below). can be called to initialize the log file, if special processing is needed. ident is a string that precedes every message. logopt is a mask of bits, logically OR'ed together, indicating logging options. The values for logopt are: Log the process ID with each message; useful for identifying instantiations of daemons. Force writing messages to the console if unable to send it to This option is safe to use in daemon processes that have no controlling terminal because forks before opening the console. Open the connection to immediately. Normally, the open is delayed until the first message is logged. This is useful for programs that need to manage the order in which file descriptors are allocated. Do not wait for children forked to log messages on the console. This option should be used by processes that enable notification of child termination via because might otherwise block, waiting for a child whose exit status has already been collected. facility encodes a default facility to be assigned to all messages written subsequently by with no explicit facility encoded. Messages generated by the kernel. These cannot be generated by any user processes. Messages generated by random user processes. This is the default facility identifier if none is specified. The mail system. System daemons, such as inetd(1M), ftpd(1M), etc. The authorization system: login(1), su(1), getty(1M), etc. Messages generated internally by daemon. The line printer spooling system: lp(1), lpsched(1M), etc. Messages generated by the system. Messages generated by the UUCP system. Messages generated by the CRON daemon. Reserved for local use. Similarly for through facility and level uses an encoded code for logging in message. The encoded code for facility and level are as follows. closes the log file. sets the log priority mask to maskpri and returns the previous mask. Calls to with a priority not set in maskpri are rejected. The mask for an individ- ual priority pri is calculated by the macro ; the mask for all priorities up to and including toppri is given by the macro (toppri). By default, all priorities are logged. ERRORS
fails if any of the following conditions are encountered: The named pipe is blocked for writing. The named pipe bold) could not be opened successfully. EXAMPLES
logs a message regarding some sort of unexpected and serious error: uses to arrange to log its process ID, to log to the console if necessary, and to log in the name of the daemon facility: Arrange to log messages only at levels and lower: Typical usage of to log a connection: If the facility has not been set with it defaults to Explicitly set the facility for this message: WARNINGS
A call to has no effect unless the syslog daemon is running (see syslogd(1M)). does not copy and store the ident string internally; it stores only a character pointer. Therefore it is the responsibility of the programmer to make sure that the ident argument points to the correct string until the log file is closed. AUTHOR
