Notation Functionality

Alarms are generated by the system in the following format:

Mon Jan 3 08:51:17 <srp> 12008 Severity 5 Comp

#mps.55/raven Line 23 Host 2 sysmon: disk space for

/var below LWM: capacity at 67%

Included in the contents of the alarm are the following fields (with their corresponding

example entries in parentheses):

•Date (Mon Jan 3)

•Time (08:51:17)

• Producer name (srp)

•Alarm number (12008)

•Severity (5)

• Component name, number, and node (mps, 55, raven)

• Phone Line number (23), if any

•Host number (2), if any

•Alarm Text (sysmon: disk space for /var below LWM:

capacity at 67%)

Each filter in a filter set can refer to the alarm fields by their fixed names: producer,

number, severity, compname (component name), compnum (component

number), node, line, and host. Filtering expressions use the following basic

C-like notation:

( logical condition ) ? actions_if_true :

actions_if_false

An expression is any syntactically correct combination of symbols that represents a

value. Every expression consists of at least one operand and can have one or more

operators. Operands are values, whereas operators are symbols that represent

particular actions (see Logical Conditions on page 209).

If no action is required, the filter should use the true or false function instead. For

example, the filter

((producer == "srp" && severity > 5) || producer ==

"vmm") ? print() : false

passes all alarms generated by srp with severity larger than 5, or generated by

vmm. The filter prints matching alarms because the print() action is invoked, and

ignores the rest. The print() action returns true, so the filter returns true if

this action is invoked, and also sends the alarm to all connected viewers.

Several filters, separated by a semi-colon (

;), can be combined into one filter set.

Each alarm is compared to all filters in the set since each filter may cause a different

action. If any filter in the set executes the action discard(), the alarm is discarded

and no further matching of the alarm is done. For example, the set

1 2 ... 202 203 204 205 206 207 208 209 210 211 212 ... 305 306
