Filtering Examples

Several examples illustrating the concepts discussed earlier are included below. While

providing a sense of the capabilities available with alarm filtering, they are by no

means comprehensive. The flexibility inherent in the programming model allows you

to develop filtering as simple or complex as required to suit your needs.

• In this example, two separate filters are combined into one filter set to log CCM

and VMM alarms into separate files and send only those alarms to the viewers:

(producer == "ccm") ? log("ccm.log") : false;

(producer == "vmm") ? log("vmm.log") : false

When an alarm arrives, it is compared to the filters in the set, in order. If the

process producing the alarm is CCM, the first part of the first filter is satisfied, the

alarm written to its respective file, and the value returned as true (resulting in

the alarm being sent on to the viewers). If the alarm is not from the CCM process,

it fails the first part of the filter and is assigned a value of false by the second

part. However, because a function of discard() has not been assigned,

checking continues through the second filter, for the process VMM, in the same

fashion as the first. If the alarm fails this check it is again assigned a value of

false and is not sent to the viewers, and no further checking is performed. The

two filters are separated by a semicolon (;).

• The following filter e-mails (internal) user peri and helpd[email protected]

with nriod alarms, but does not send them on to the viewers because neither

filter returns a value of true (even though an alarm may satisfy the producer

portion of the filter, the filter itself assigns a value of false through the &&

false expression). Any alarm not produced by either process is also kept from

being sent to the viewers due to the secondary false statement. The flow from

filter-to-filter occurs in the same manner as that in the previous example.

(producer == "mxvmt") ?

(email("MXVMT alarm", "peri")&& false):false;

(producer == "nriod") ?

(email("nriod alarm", "helpdesk@nni.com")&&

false):false

• In this instance, all commgr alarms are logged to a file located in /home/user,

but not sent to the viewers or checked further due to the discard() function.

All other alarms, however, are sent to the viewers because the second portion of

the filter always returns a value of true.

(producer == "commgr") ?

(log("/home/user/commgr.log") && discard()) : true
