Introduction
In NMIS/opCharts we can add custom validations for custom fields.
This is a list of the steps the customer needs to follow :-
1)Add the custom field name to NMIS, in this example we are using "Device CI" as our custom field name.
/usr/local/nmis9/conf-default/Table-Nodes.nmis
{ device_ci => { header => 'Device CI', display => 'header,text',value => [""] }},
2)Modify the node_summary_field_list list attribute in /usr/local/nmis9/conf/Config.nmis
'node_summary_field_list' => 'host,uuid,customer,device_ci,businessService,serviceStatus,snmpdown,wmidown',
3)add a custom_indices field in Config.nmis.
Config.nmis::database::
'custom_indices' => {
'nodes' => [
[ {'configuration.device_ci' => 1}, { unique => 1, partialFilterExpression => { "configuration.device_ci" => { '$exists' => true } } }]
]
}
Then verify by running the following command
perl -c /usr/local/nmis9/conf/Config.nmis
4)After the addition of custom indices, please run ensure indexes to add custom index.
/usr/local/nmis9/bin/nmis-cli act=ensure_indexes debug=9
/usr/local/nmis9/bin/nmis-cli act=ensure_indexes debug=9
5)Add the Device Ci to the admin node table
/usr/local/omk/lib/json/admin/table_schemas/admin_node-ip.json
{
"name": "nodes.configuration.device_ci",
"label": "Device CI",
"cell": "String",
"editable": false,
"search": "iregex"
}
6)Add the Device Ci to the opCharts node table
/usr/local/omk/lib/json/opCharts/table_schemas/opCharts_node-list.json
{
"name": "nodes.configuration.device_ci",
"label": "Device CI",
"cell": "String",
"editable": false,
"search": "iregex"
}
7)Add the Device Ci to the admin edit node fields. (admin_nodes.json file will need to be created in the "/usr/local/omk/conf/form_schemas/" directory )
vi /usr/local/omk/conf/form_schemas/admin_nodes.json
{"label": "Device Ci",
"description": "Edit in conf/form_schemas/admin_nodes.json",
"component": ["node_admin"],
"tags": ["node"],
"schema": {
"configuration.device_ci": {
"title": "Device CI",
"type": "Text"}
}}
}
8)Add the device_ci to omk/opCharts/nodes so it shows in the node info table
vi /usr/local/omk/lib/json/opCharts/table_schemas/opCharts_node-summary-table.json and add the device_ci as shown below
// VERSION=1.518.0
[
"group",
"host",
"host_addr",
"location",
"nodeVendor",
"nodeModel",
{ "name" : "device_ci", "label": "Device CI", "cell": "String"},
{ "name" : "sysDescr", "label": "sysDescr", "cell": "Tooltip", "formatter": "ShortenedString", "maxLength" : 48},
{ "name" : "lastUpdateSec", "label" : "Last Updated", "cell" : "String", "formatter" : "UnixTime"},
{ "name" : "sysUpTimeSec", "label" : "Uptime", "cell" : "String", "formatter" : "UpTime"},
{ "name" : "remote", "label" : "Managed by"}
]
3)New validation plugins are present at
we have a directory
/usr/local/nmis9/conf-default/plugins/
the plugin is present in
/usr/local/nmis9/conf-default/validation_plugins/
Now we need to do is
create a directory
/usr/local/nmis9/conf-default/plugins_available/
then create a soft link of that file in plugins
/usr/local/nmis9/conf-default/plugins/
Commands to use
cd /usr/local/nmis9/conf-default/
mkdir plugins_available
cp /usr/local/nmis9/conf-default/validation_plugins/NodeValidations.pm /usr/local/nmis9/conf-default/plugins_available/
cd plugins
ln -s /usr/local/nmis9/conf-default/plugins_available/NodeValidations.pm NodeValidations.pm
sudo service nmis9d restart
sudo service omkd restart
