evmﬁlterﬁle(4) evmﬁlterﬁle(4)

The previous ﬁlter lines are equivalent to this more complex single ﬁlter line:

value "([priority >= 200]) OR [name *.mylog] AND NOT [name *.oldlog]"

The ﬁrst line selects all events with a priority of 200 or greater, the next modiﬁes this by selecting all

events from mylog regardless of their priorities, and the last line excludes all

oldlog events regardless

of their priorities.

If you prefer, you can omit the

value

command, and build the complete ﬁlter string from include and

exclude lines.

Notes

If you are concerned with allowing your ﬁle to be used on other systems that support EVM in the future,

you should use the built-in macro

@SYS_VP@ in place of the ﬁrst two components (

sys.unix) of the

name of any system event. This will make it unnecessary to change the ﬁle if the other system uses a

different event name preﬁx.

EXTERNAL INFLUENCES

Environment Variables

EVM_FILTERDIR

A colon-separated set of directory pathnames to be searched for a requested ﬁlter

ﬁle. If this variable is present in the environment the directories are searched in

place of the standard directories.

EXAMPLES

1. The following is an example of a pair of entries in a ﬁlter ﬁle:

# Select all events posted by myapp, excluding any that

# have a priority lower than 200:

filter

{ name myapp

value "[name myco.myapp.*]"

exclude "[pri < 200]"

title "All myapp events"

}

# Select all events posted by myapp, and important system events:

filter

{ name sys_myapp

value "[name myco.myapp.*] | \

([name @SYS_VP@.*] & [priority >= 400])"

title "System errors and myapp events"

}

2. The following command ﬁnds and displays all EVM events, using a ﬁlter stored in the supplied ﬁlter

ﬁle /usr/share/evm/filters/sys.evf

evmget -f @sys:evm | evmshow

3. Assuming that the ﬁlter ﬁle shown in the ﬁrst example is named myapp.evf and is located in a stan-

dard ﬁlter directory, the following command displays the value of the sys_myapp ﬁlter from that ﬁle:

evmshow -F -f @myapp:sys_myapp
