The Machines and Devices pages contain a powerful interactive search bar that lets you filter machines and devices. This article is designed to help you understand how to use this resource.
This article will explain:
- How to do simple searches
- How to do filtered searches
- How to create manual filters
- How to set up exact matching
- How to set up partial matching
- How to include multiple search terms
This article also includes a filter properties reference
A valid MAAS search parameter looks like this:
Each search attribute is placed in the Search box, separated by spaces (if it’s an “AND” search operation), or by parentheses and commas (if’s it’s an “OR” operation). Specific search parameters use the notation “parameter-name” followed by a colon (":"). For example, here we’re searching for “pod:”, which equates to the pod name (VM name).
You can match exactly by using the equals sign ("=") with a filter fragment, or make a partial match by excluding the “=”. You can get an idea how these parameters work by using the filter drop downs in the UI, which generate a valid search expression in the “Search” box. There is also a “not” operator ("!") which can be applied to partial or exact matches.
Enter text in the Search box. As you type, MAAS will update search results in real time. You can search across virtually every parameter, including domain, name, tag, power type, IP, status, zone, and so on.
Select the Filters drop-down.
Choose a parameter group. The group will lock open.
Choose one or more parameter values to search against. MAAS will update the search results in real time.
Enter filters manually in the search bar to more precisely control your searches:
Note: Surround search terms with parentheses when they must occur together, e.g.,
If you need an exact match, preface the search value with an equal sign. For example, to find machines belonging to a pod named
Without an equal sign, MAAS returns partial matches. For example, the following will display all machines belonging to pods with names containing
MAAS uses Boolean AND logic to evaluate multiple search terms. For example, when you type
pod:able,cattle cpu:=5, MAAS displays machines that belong to pods with names containing
cattle AND having 5 CPU cores. Similarly, if you enter multiple words into the search tool, e.g.,
steady able, MAAS will display machines matching both terms (e.g.,
The following table describes the expanded filter set for the MAAS machine list:
- Items marked “Dyn” are dynamic, populated based on existing data, that is, the “Tags” filter only shows tags that currently exist.
- Items which are not dynamic present the entire range of possible values, regardless of whether that value currently exists in MAAS; for example, all machine status values are available to be filtered, even if no machines currently have that status.
- Items marked “Grp” can be used to group machines, instead of the default machine status.
- Items marked “Man” must be manually entered, i.e., they are not in the UI filter drop-down, but can be entered in the “Search” box if properly formatted (as in the examples given).
