Tagging Entities. An ITNM discovery tool for improved monitoring and visualizationIn social media, the phrase 'tagging' scares us. There is a potential that unwanted attention will be brought upon us. However when we review the tagging of entities in an IBM Tivoli Network Manager (ITNM) discovery, these tags will give special attention to entities. These tags allow for some unique monitoring and visualization capabilities. A file finder discovery is based upon a flat file on the ITNM core server. This is very common and is typically a list of names and IP addresses. Take a look at my Halloween themed flat file.
[root@server precision]# cat /etc/ghosts I discover three servers, but I have included an additional 'tag', I call okpoll My goal is that I don't want to continually manipulate my device filters in my poll policy, but have devices I poll predetermined by my file finder file. I'm interested in polling ServerWest and ServerEast, but not ServerCentral.
Here are the changes to populate my tags, in $NCH
Disc
insert into file
DbEn
insert into dbMo Service disco will show these tags are available after the discovery
|server:1.> select * from scra These tags carry from discovery to model and are finally placed in ncim
|server:1.> select * from ncim.entityDetails;
No extension of the ncim database is necessary! Take a look at the documentation and create a network view for the Pollflag->okpoll
Crea So many options are now available. Poll only the devices that are 'okpoll'. This is done by polling on the specific view I created based on the tag in the above link. Create a view based upon a tagged entity And entities can be tagged not only from the file finder, but also based upon Or tagging based upon a subnet Continue to check the IBM Education Assistant page for a future detailed presentation of tagging.
