The invention discloses a Linux real-time
alarm device, which adopts the steps that: an asynchronous response module receives an asynchronous request sent by a
client, wherein the asynchronous request comprises subscription alarm information; an alarm acquisition module acquires
system alarm data regularly according to the asynchronous request; an alarm
database storage
system alarms
metadata and the
system alarm information; an alarm
processing module determines system alarm information corresponding to the system alarm data by utilizing the alarm
database, and sends the alarm information to the
client. The device can regularly acquire the system alarm data after the
client opens subscription alarm, and has very high real-time performance, and thus, a user can receive the system alarm information at the first time; the Linux real-time
alarm device overcomes the defects of a conventional C / S
architectural pattern and a general B / S architecture in monitoring alarm and real-time performance, and is simple in function expansion and easy to use; the invention further discloses a Linux real-time alarm method and system and a
server, which have the effects above.
