Tables

Tables allow for analysis and correlation of network state information and parameters on the fly. Most of the tables display live snapshot data generated by graph algorithms without pre-existing cache. The first load of a table usually takes longer than subsequent loads, but all tables were built to handle a large capacity and complex queries, so the outcome should be better than analyzing the output in an external application like Excel.

Working with tables

The ARP Table (in Technology → Addressing → ARP Table) is used as an example below to demonstrate the functionality of tables.

Table Description

By clicking ... (3-dot button in the top-right corner of the table) and selecting Table description, you can get a short description of the current table along with API examples.

Export to CSV

The current table view can be exported to CSV. This is useful for additional data processing in an external application.

Contextual Help

Contextual help (tooltip) is displayed when the mouse cursor hovers over a table header text or a table icon.

Searching for Data

Filters will change what is displayed in the table, the exported CSV data, and the API documentation found in the Table Description.

Simple Filtering

In most columns, you can type in what you are looking for. The example above shows a search for all devices with an IP address starting 10.67.254 throughout all the ARP tables in our lab environment.

Use this button to clear the filter:

Advanced Filtering

If you need a more precise filter, use Advanced Filter.

Filters are defined by groups and rules. Each group can contain one or more rules or another group. There is always one root group which cannot be deleted (group 1). Select the logical operator for each group. The example above shows logical Or for group 1 and logical And for groups 2 and 3.

What does the example above do? It shows all devices with hostname L47AC8 AND interface Et7/2 as well as devices with hostname L43SD73 AND interface Et13/0. In other words: “Show me all devices with hostname L47AC8 which have interface Et7/2, plus all devices with hostname L43SD73 with interface Et13/0.

Using The Standard Metric Notation On Filtering

Trying to filter the values in the number columns using Simple Filtering or in the Advanced Filters, you can type not only numbers to filter, but some measure prefixes (like 10 k, 15M, etc.):

or

You can find the table with available prefixes below:

Symbol	Name	Base 10	Decimal
`P`	`peta`	10¹⁵	1000000000000000
`T`	`tera`	10¹²	1000000000000
`G`	`giga`	10⁹	1000000000
`M`	`mega`	10⁶	1000000
`k`	`kilo`	10³	1000

The table view can be shared with other users.

Intent Verification Rules (Colorizing Columns)

The table column can be colored based on pre-defined rules. The existing (as well as the default) rules are visible above the table and can be edited or removed.

To create a new rule, you need to specify its Rule name and select a Colorized column. Adding the rule to a dashboard widget will enable it to be displayed on the Dashboard, but this is optional (check the Dashboard page for more details).

Finally, specify a filter rule to colorize the selected column:

Choose a color to apply rules to.
Add rules based on the same logic as described in Advanced Filtering.
A color can be designated as the Default color which means that it will be used if no other rules are matched.
Click Update rule or Create rule to save your changes.

In the example above, all items in the VRF column which are named VRF1 will be colored red. A summary number of items which matches this rule will also be displayed in the Interfaces widget on the Dashboard.

Display settings

In Display Settings, you may select what columns are displayed. This will also change the behavior of Export to CSV and the API documentation in the Table Description.

Auto size

Auto size (enabled by default) ensures that columns are automatically sized to fit their current content each time the table is opened.

By disabling Auto size, columns will remember user-defined widths.

Restore table settings

Table filters and other settings can be restored using the Restore table settings option. Colorization rules will not be removed!
