The Monitoring > Resources Status page is your main view to track resources events & statuses, analyze & quickly handle them.
This view mixes hosts & services to have a unified interface and way to manage events.
The event list is a condensed and efficient view of all alerts and of the status of all resources monitored by Centreon.
You can add or remove columns, and sort by the column of your choice.
Take actions on events
Acknowledge an event
When one or more alerts are visible, you may need to acknowledge them to tell your team that the problem is handled. You can do that in two ways:
- By directly acknowledging the line: an Acknowledge button appears on mouseover
- By selecting multiple lines and clicking on the Acknowledge button above the table.
Only "non-ok" resources can be acknowledged and you cannot acknowledge a resource that has already been acknowledged.
When a resource is acknowledged:
- The alert is not visible anymore in the Unhandled problems filter
- Notifications for this resource are stopped
- The color of the line for acknowledged resources is changed to yellow.
The acknowledgement can also be cancelled, in which case the event will be included again in the list of Unhandled Problems and its notifications will resume: in the More actions menu, select Disacknowledge.
Set a planned downtime
When a maintenance is planned on one or multiple resources, you can set a planned downtime for them in Centreon in two ways:
- By directly setting a planned downtime on the line: a Set Downtime button appears on mouseover
- By selecting multiple lines and clicking on the Set Downtime button above the table.
When a resource is in planned downtime, the alert is not visible anymore in the Unhandled problems filter and notifications for this resource are stopped. The color of lines for resources with a planned downtime is changed to light purple.
Refresh a status
In many situations, you need to quickly re-check one or multiple services to refresh their status. This can be achieved in two ways:
- By directly clicking on the Check button on the line when the mouse is over
- By selecting multiple lines and clicking on the Check button, above the table.
Submit a status
In some cases, especially with so-called "passive" services, it can be useful to submit a result, i.e. a status, an output and metrics, in order to reset the event. This can be achieved using the Submit Status action, available when a single passive service is selected.
When you open the Resource status page, the default filter is Unhandled problems. This filter quickly shows all problems/alerts that are not yet handled so you can focus on choosing the most relevant alerts to take care of. You can choose two other filters that are Resources problems and All.
The following rules apply:
- Unhandled problems: resource status is Warning or Critical or Unknown or Down AND the resource is not acknowledged nor in planned downtime
- Resource problems: resource status is Warning or Critical or Unknown or Down (whether or not the resource has been acknowleged/a downtime has been set)
- All: All resources.
You can filter the list of resources by their name. Regular expressions are supported. By default, the search bar will look for your expression to match with:
- Host name
- Host alias
- Address or FQDN
- Service description
It's possible to force searching on specific fields by using the following labels:
- h.name: only search in the host name field
- h.alias: only search in host alias field
- h.address: only search in the host address field
- s.description: only search in the service description field
- information: only search in the information field
If pre-defined filters and the search bar are not enough, it's possible to expand the filter bar to access the following additional criteria:
- Resource type: host, service or meta-service
- Status: OK, Warning, Critical, Unknown, Pending, Up, Down, Unreachable
- State: Is the problem already acknowledged, in a planned downtime or simply unhandled
- Host group
- Service group
- Monitoring server: resources monitored by a specific server (or poller)
You can hide or display the search criteria you want: use the Select criteria button to the left:
Save your filter
You may create some "complex" filters that set you in a specific context, using multiple criteria and even complex regular expressions. In that case, you may want to save this filter and re-use it later.
Use the gear icon next to Filter to:
- Save your current search as a new filter
- Save the current filter so that it is updated using the criteria currently applied
- Edit filters so that you can rename, re-order or delete them
As soon as a filter is saved, it can be reused in the Filter dropdown list, categorized under My Filter.
By clicking on the Edit filters menu, you can manage your existing filters (rename, re-order and delete):
When you click on a line, a detail panel opens on the right side to display the main information concerning the resource. This panel can be resized.
Depending on the type of resource, the detail panel displays different information.
The host panel contains the following elements:
- Details tab: Detailed information about the host's current status,
- Services tab: A listing of its attached services and their current status (as well as their graphs if the corresponding mode is selected),
- Timeline tab: The timeline of events that occurred for this host,
- Shortcuts to the configuration, logs and report for this host.
If an acknowledgement or downtime is set on the host, it will be displayed in the panel and the header will be colored accordingly.
The service panel contains the following elements:
- Details tab: Detailed information about its current status,
- Timeline tab: The timeline of events that occured for this service,
- Graph tab: A graph with one curve per metric collected by this service,
- Shortcuts to the configurations, logs and reports for this service and its related host.
If an acknowledgement or downtime is set on the service, it will be displayed in the panel and the header will be colored accordingly.
The graph tab enables you to visually display how the metrics evolve for the selected resource.
Hovering over the metric curves will display under the graph's title the precise time and also display within the legend the different values for that same point in time.
When the pointer is not hovering over curves, the legend displays Min, Max and Average values for each metric.
Use the legend to display or hide metrics:
- Click on a legend item to display only the corresponding metric.
- To display all metrics again, click again on the legend of the displayed metric.
You can also toggle the selection of individual metrics by Ctrl+Clicking (or Cmd+Clicking for Mac users) on the corresponding tile within the legend:
Graphs display metric evolution over a given period of time. This can be defined in the following ways:
- A selection of preconfigured periods is available in the graph header: Last Day, Last 7 Days, Last 31 Days
- Datetime pickers are available for Start and End points in time. Anytime the displayed period changes, this element is updated accordingly
- Using the side [<] and [>] buttons that appear upon hovering the graph's border, you can translate in time by half your current timespan (respectively backward and forward in time)
- Selecting a period of time within the graph will zoom in on this period
The Display events toggle (available under the gear button) allows you to display some timeline events (downtime, acknowledgement, comment) directly on the graph, via annotations:
It is possible to add a comment directly on the graph, by left clicking anywhere at the time you want to add it, and select Add a comment on the tooltip that appears:
To delete a comment, go to Monitoring > Downtimes > Comments.
By clicking on the Export to PNG button, you can export a snapshot of the graph, which also includes the timeline events, if the switch is toggled. Note that only the selected metrics will be exported:
