Posted by Peter Choi Draw Your Infrastructure Last month, we introduced our new host view that gives users the flexibility to group and filter their hosts based on tags. Today, we’re excited to announce a complementary view: the host map! The host map allows intuitive assessment of infrastructure health so you can group, filter, and “color” hosts based on tags and metrics you care about. If you want to glance over your infrastructure and visually identify outlier hosts quickly, then the new host map will serve you well. Using the Host Map Accessing the Host Map The new host map is accessible via the host view. You’ll see a link called “View Host Map” at the bottom of the page. Host list showing link to view host map (at the bottom). Once you access the host map, you’ll see a default view showing all the hosts sorted by CPU utilization, based on data gathered by the AppOptics™ Host Agent. This allows you to quickly identify hosts that are running hot by just looking at the individual host’s gradient color (darker means higher utilization). Host map showing all hosts by CPU utilization. Click on an individual host to open up the host card, which contains detailed information about the host, like system info, network info, KPIs, plugins, services, and tags.

You may not always want to see your hosts based on CPU utilization. For example, you may want to see your hosts based on memory utilization, disk, or network I/O. The host map provides an easy way to accomplish this. You can select any metric via the “Fill By” input to color your hosts. Select your own KPI to color the hosts. Grouping and Filtering Hosts We applied the same grouping and filtering capability available on the host list to the host map. This means that you can apply up to three tags for grouping your hosts, in addition to any filters narrowing the focus. The host map below shows hosts grouped by region, instancetype, and plugin tags, respectively. Host map grouped by region, instancetype, and plugin tags respectively. The host list obeys the same group and filter settings, and you can toggle back and forth as needed. Identifying Hosts that Belong to the Same Group When you group hosts using multiple tags, it logically results in nested groups. For simplicity, the resulting groups are flattened and presented as distinct, individual groups. As you can see on the diagram below, every permutation of the region, instancetype, and plugin is presented as an individual group. Hovering over the Hosts Group label shows a tooltip with grouping hierarchy When you hover over the group label, a tooltip containing a hierarchical structure of the grouping is displayed. You can click on any group on the shown hierarchy and the host map will select all hosts that fall under that group. Selecting the group on the hierarchy highlights all hosts belonging to that group on the map and opens up the hosts group card to show summary information. Conclusion Whether you want to quickly find metric hot spots across your infrastructure or see relative infrastructure provisioning and utilization, the host map has you covered. The best way to experience the host map is to actually use it. Go ahead and give it a try!
