Monitors are information available on a device, such as CPU, memory, disk, etc. Each device exposes specific resources that can be monitored. The colors of the monitors vary according to their state.
Real-time Chart: Displays the chart updating its data at the selected time interval.
Sampling Period: Customize the period of the chart to be generated.
Chart Properties: Opens the screen with the properties of the displayed chart.
Ícone
Descrição
Title: Name that will appear at the top of the chart.
Limits per reading: When enabled, fills the entire chart according to the period status during readings.
Show Status Markers: When there is a status change in the presented time period, Monsta adds a mark to show when and to which state the change occurred.
Hide values: Removes the reported values from the bottom of the chart display.
Hide legend: Removes the legend from the chart display.
Show variation only: Renders the chart only with its variations for better visualization of changes.
Legend color: Customizes the text color of the legends at the bottom of the chart.
Background color: Customizes the chart background color.
Legend font size: Customizes the size of the legend at the bottom of the chart.
Line width: Customizes the width of the line rendered on the chart.
Show Percentile Indicator: Adds the selected percentile to the chart.
Group Data by Time
Group data by time: When there is a time period longer than two days, Monsta groups data and automatically generates an average of the information to be presented on the chart. In this property you can choose the time this grouping will use or simply disable this property.
Metric Value: Shows the metric name, the current reading value and whether the result is higher, lower or equal to the previous reading.
Metrics: Displays information about each individually monitored resource.
Edit: Changes the properties of the selected monitor.
Delete: Deletes the selected monitor.
Publish: Creates a link to publish the chart without requiring authentication. For more information, see Publish a Monitor
Number of Attempts: Indicates the number of attempts the monitor will make before leaving the normal state.
Monitor Information: Displays the date of the last check, the date of the next check, the last status change and the date of the last sent alert.
Percentage: Displays the percentage of the resource used by the selected metric when a maximum value is provided.
Export / Calculate Area: The data collection chart offers three main options for interacting with the visualized data:
Export as Image: In the top right corner of the chart, click the “Download” or “Export” icon to save the chart as an image file. This allows you to use the image in reports, presentations, or easily share it.
Export Data: You can export the raw data in spreadsheet formats for later analysis. Available formats are CSV and XLS.
Consumption Report: For more in-depth analysis, you can calculate the area under the chart curve. This function is ideal for obtaining accumulated or total values over the selected period. Click the “Consumption Report” option and the result will be shown in a text box, ready to be copied or used in your calculations.
Editing a monitor allows customizing important information about its behavior, such as collection frequency, alert thresholds and its script for how to fetch the information.
Icon: Allows selecting the icon that will be displayed on the screen.
Short name: This is the text that will appear on the monitor icon.
Name: This is the text that will be shown at the top of the monitor chart.
Metrics: These are the resources whose data will be collected for the chart.
Color: Selects the color that will be rendered by the metric on the chart.
Metric name: The name that will be shown in the legend of the current reading indicator.
Legend: The name that will be shown in the chart legend and in the current value indicator for the selected metric.
Instances: Allows switching the current instance of the metric.
Clone: Allows adding a new metric to the same monitor.
Disable Thresholds: When checked, disables alert sending for the monitor being edited. The selected metric will always be considered in a normal state.
Fix OID: When unchecked, Monsta will verify whether the name of the monitored instance remains at the same OID, and in case of change, the new position will be located automatically. When this option is checked, Monsta will collect data always from the same OID, regardless of the instance name.
Threshold Inversion: This option allows you to change the alert logic of a monitor. Use this feature for metrics where a low value indicates a problem (e.g., the speed of a network interface should not drop below a certain level) or where you need to monitor specific ranges of values.
Alert Percentage: Allows selecting at which values the metric will enter an alert state. When a maximum value is defined, alert configuration will be in percentage; otherwise, limits are provided as numeric values.
Check Interval: Allows selecting how frequently the monitor will run.
Number of Attempts: Allows selecting how many times the monitor should be checked before leaving its normal state. When a monitor returns to normal before reaching this limit, this counter is reset. |
Notify alert group: When enabled, sends alerts to the selected groups; otherwise, Monsta will not send alerts even when the monitor changes state.
Inherited from the device: These are the alert groups defined in the device edit. Once inherited, they cannot be removed from the monitor, only disabled.
Add Alert Group: Adds groups that will receive alerts when the monitor changes state. For more information see Alerts.
Remove Alert Group: Removes the selected alert group.
Shows the last failures that occurred during the monitor’s collection. This record is useful to understand why a collection might not be completing successfully.
