Host Views

The Explore tab is the screen you will see when first logging in and displays an ‘at-a-glance’ status of your entire infrastructure.  From Explore, you can quickly visualize the health of all infrastructure components - grouped or individually - in graph, table, and map formats, from a variety of host and cloud services ‘views’.   

By default, the host view 'Overview' is displayed listing all of your instances with current, real time resource usage metrics. All of the hosts and cloud services views have a similar layout but with unique usage and performance metrics for the specific resource under analysis. And, all metrics are updated with 1 second granularity!

 

Explore View Selector

The Explore View Selector surfaces different ways of looking at your infrastructure.  Change the category of metrics displayed by selecting from the menu of host and cloud provider service sidebar menu:

 

 

 

Two categories of views are available, metrics coming from the Sysdig agent installed on your instance report to the hosts views.  If you have your cloud provider integrated with the Sysdig Monitor service and have enabled polling (Settings > Cloud Providers), the cloud provider views allow reporting on your infrastructure independent of our agent. 

Hover over the ‘i’ information icons to see tooltips with descriptions, usage tips and field listings for each of these top level host and provider views.

The different views you can select are below along with brief descriptions:

 

HOSTS

Description

Overview (default)

This default table gives a 'birds-eye-view' of your entire computing infrastructure. All host instances are listed with major resource usage metrics (CPU, Memory, Network, etc).

CPU/Memory

Several important metrics are listed in this table view that can cause application performance problems including stolen CPU time, memory faults and paging.

Requests Time Breakdown

Server processes are listed per instance with transaction processing metrics showing the amount of time (in %) transactions are spending in the next tier as well as the amount of local resources consumed by the transactions.

Network

The number of current connections and total amount of network traffic, broken down for both directions, is shown by server processes per instance.

File I/O

This view shows file system capacity usage, the amount of data written to and from storage and the number of I/O calls needed for that data.

Requests

This view shows transaction counts and performance metrics by instance or process.

Forecast

This view shows CPU% capacity usage and transaction requests and estimates the loss of capacity to service requests due to 'stolen cpu'.

AWS SERVICES

Description

EC2 Instances

General EC2 Instance information as reported by AWS EC2 service.

RDS Instances

General RDS instance information as reported by AWS RDS.

ELB Instances

General ELB instance information as reported by AWS ELB.

ElasticCache Instances

General ElastiCache instance information as reported by AWS ElastiCache service.

 

Grouping Function

Grouping is a powerful concept in Sysdig Monitor that allows you to view your infrastructure in a way that makes the most sense to you.  Up to 3 logical tiers (levels of hierarchy) can be selected in the group-by function, meaning you can combine different groupings together at once.  Tags are either default, assigned when the Sysdig agent is installed (optional) or come from your cloud provider which may also be optionally assigned when the instance was installed.

To organize your infrastructure, click the ‘+’ symbol next to “Group By” at the top of any host or provider top-level view and select a grouping from the list presented. Repeat twice for up to three levels of hierarchy and see your infrastructure list rolled up into the chosen groupings.  You can then click on the group in your list to see aggregated metrics for it or click the ‘+’ symbol to expand the group further to the next level or actual instance or container.

 

  

 

Some example default groupings in Sysdig Monitor are listed below along with a short description of what that grouping does. The list will expand if you assign additional tags when installing our agent or assigning tags at the cloud provider’s control panel:

 

GROUP NAME:

HOSTS GROUPED BY:

No grouping

Nothing, hosts listed in order of IP address.

agent.tag.$NAME

An optional user-defined label assigned during the Sysdig agent installation.

cloudProvider.securityGroups

Name of security group

host.domain

Host’s DNS domain name

host.isClientServer

Function of host: ‘client’ or ‘server’

host.procList.main

Primary resource consuming process on the host

instance.type

Hardware specification type of AMI (Amazon Machine Image)

region

Geolocation of physical Amazon cloud infrastructure.

 

 

After selecting the host or service provider view, configuring your grouping and then clicking on any group or instance, you will see a second ‘drill-down’ view appear underneath the top-level view.  The large selection of drill-down views give you a substantially more detailed picture of the group or instance selected and will be discussed in the next section.
