upsdrvctl - UPS driver controller
upsdrvctl [-t] [-v] (start | stop | shutdown | status) [ups]
upsdrvctl provides a uniform interface for controlling your UPS drivers. The intention is for users to always use upsdrvctl for starting and stopping them rather than hard-coding driver calls into their startup scripts.
When used properly, upsdrvctl lets you maintain identical startup scripts across multiple systems with different UPS configurations.
upsdrvctl supports three commands - start, stop, and status. They take an optional argument which is a UPS name from ups.conf(5). Without that argument, they operate on every UPS that is currently configured.
If every UPS that has been checked is running, then the exitcode will be 0. If one seems to be missing, the exitcode will be 1.
Old drivers can't be controlled with upsdrvctl. While many popular drivers have been converted, there are still a number that have not. If your hardware uses an older driver, you must call it directly.
You can find out if your driver is new or old by starting it with -h to see the help text. If it mentions '-a' to autoconfigure, then you have a new driver. Otherwise, it's old.
In this case, consider converting the driver yourself, then send in a patch.
The status checking is rudimentary, and really only looks for the presence of .pid files. If you really want to know if your UPS drivers are alive and well, upsmon(8)'s NOCOMM notifier does a fine job.
