If you enable the File finder to seed your discovery, then you can add name-value pairs
to entities by adding extra columns to the seed file read by the File finder.
About this task
The example procedure below assumes that you are adding the
following extra columns to your File finder seed file:
The following example text file fragment shows what the seed
file might look like:vi /var/tmp/logged_hosts
172.16.1.21 lnd-dharma-acme acme london
172.16.1.201 lnd-phoenix-acme acme london
172.16.1.25 prs-sun-acme acme paris
172.16.2.33 ranger1 telecorp newyork
172.16.2.34 ranger2 telecorp newyork
~
"/var/tmp/logged_hosts" [Read only] 4 lines, 190 characters
In
this example text file fragment, the third column holds customer information,
and the fourth column holds location information.
Procedure
- Edit the DiscoFileFinderParseRules.cfg configuration file.
- In this configuration file, configure the File finder to
parse the seed file using an insert similar to the example. Ensure
that you configure the
m_ColDefs
field to match the
new custom tag columns. insert into fileFinder.parseRules
(
m_FileName,
m_Delimiter,
m_ColDefs
)
values
(
"/var/tmp/logged_hosts",
"[ ]",
[
{
m_VarName="m_UniqueAddress",
m_ColNum=1
},
{
m_VarName="m_Name",
m_ColNum=2
},
{
m_VarName="m_CustomTags->customer",
m_ColNum=3
},
{
m_VarName="m_CustomTags->location",
m_ColNum=4
}
]
);
This
insert instructs the File finder to do the following:
- Parse /var/tmp/logged_hosts.
- Treat white space as the data separator.
- Use the following column definitions:
m_UniqueAddress
for the first column
m_Name
for the second column
m_CustomTags->customer
for the third
column
m_CustomTags->location
for the fourth
column
- Edit the DbEntityDetails.cfg file and configure an insert
similar to the following:
insert into dbModel.entityDetails
(
EntityType,
EntityDetails
)
values
(
1, -- chassis
{
Customer = "eval(text, '&m_ExtraInfo->m_CustomTags->customer')",
Location = "eval(text, '&m_ExtraInfo->m_CustomTags->location')"
}
);
insert into dbModel.entityDetails
(
EntityType,
EntityDetails
)
values
(
2, -- port/interface
{
Customer = "eval(text, '&m_ExtraInfo->m_CustomTags->customer')",
Location = "eval(text, '&m_ExtraInfo->m_CustomTags->location')"
}
);
- Restart Network Manager to
propagate the configuration file changes:
itnm_start ncp -domain domain
-
Run a full discovery using the File finder to discover your network with the
name-value pairs added.
What to do next
Ensure that the new data is propagated between discoveries.
