Timezone

The timezone setting can be used when having a recurrency period enabled. This makes sure the schedule and report time is correct for your timezone.

Retention policy

Under the timezone dropdown, the retention policy of the report can be specified. This specifies how long the report will be stored. After this period, Capture will auto delete your report. The default value is 30d.

Grafana panel

How to Get the URL of a Grafana Panel

To find the URL of a specific Grafana panel:

1. Navigate to your Grafana Dashboard.
2. In the upper-right corner of a panel, click the three dots (menu icon).
3. Select the "Share" option.
4. Under the "Link" tab, you will see the "Link URL" field.
5. Copy the URL from the "Link URL" field and use it in your report panel.

This URL can be used in the report panel of your data platform to link to the Grafana panel.

How the from and to Fields Work

The from and to fields accept relative time expressions that are parsed to determine the start and end of the range. The expressions can use the following components:

• now: Refers to the current time.
• -xd: Refers to x days ago.
• -xw: Refers to x weeks ago.
• -xM: Refers to x months ago.
• -xY: Refers to x years ago.
• /d, /w, /M, /Y: When combined with the above expressions, the / specifies the start (beginning) of the given day, week, month, or year.
• +Nh, +Nm: Adds additional hours (h) or minutes (m) to the base time expression to pinpoint exact time ranges.

caution

When using the / symbol, always write now before -...!

The / Symbol for Day-Based Expressions

When the / symbol is used in the from or to fields, it moves the timestamp to the start of that specific day (in the case of from) or the end of that day (in the case of to). This is especially useful when you want to capture a range of data for a specific day or a specific time frame within that day.

Adding Hours or Minutes with /

To capture more specific times (e.g., data between 9:00 and 9:40), you can use the +h (hours) or +m (minutes) syntax. When using these with the / symbol, hours and minutes are added after jumping to the start (for from) or end (for to) of the specified day.

Special Considerations for the to Field

Since the to field uses the end of the day in conjunction with the / symbol, you must subtract an additional day to account for the shift when specifying time ranges with hours and minutes. This can be unintuitive, so here’s how to handle it:

• For the from field: Specify the exact day and time (e.g., now-3d/d+9h for 9 AM three days ago).
• For the to field: Specify the previous day when targeting specific times (e.g., now-4d/d+580m for 9:40 AM three days ago).

Examples

1: Fetch Data from Today

• from: now/d
• to: now/d

This will fetch data from the start of the current day (midnight) to the current time.

2: Fetch Data for Yesterday

• from: now-1d/d
• to: now-1d/d

This will fetch data from the start to the end of yesterday.

3: Data Between 9 AM and 9:40 AM Last Friday Assume today is Monday.

• from: now-3d/d+9h (This refers to Friday at 9:00 AM)
• to: now-4d/d+580m (This refers to Friday at 9:40 AM)

Explanation:

• In the from field, now-3d/d+9h takes us to the start of Friday, then adds 9 hours, landing exactly at 9:00 AM.
• In the to field, now-4d/d+580m moves back 4 days (to Thursday’s end) and then adds 580 minutes, which brings us back to 9:40 AM on Friday.

4: Data for the Last Week

• from: now-1w/w
• to: now-1w/w

This will capture data from the start of the previous week (Monday) to the end of the previous week.

How it Works

1. From Field:

   • The expression now-xd/d moves to the start of the day x days ago. Adding +Nh or +Nm moves forward by hours or minutes.

2. To Field:

   • The expression now-xd/d shifts to the end of the day (23:59:59) x days ago. Adding +Nh or +Nm similarly moves the time forward from midnight.

Tags

Tags are not necessary to use in the Capture system, but we strongly recommend making a habit of applying them to your configurations. In reporting, they can be used to seperate reports or report sections for different tag values while using the same configuration. When looking at our bottling example, we have four different bottling machines. We could choose to collect all data from the machines in one report or we could generate one report for each machine.

Generating seperate reports

In the content section of the configurations editor, click + add tag variable. Select the database and choose a tag key, then add the values you want to generate reports for. If you select PDF Key, a different report will be created for each tag value. In our Bottling example, we have a tag that was created in the device configuration named Machine, this has four values (1, 2, 3 and 4) that represent each machine.

Using tags in the query

While creating a query for the data in a section, you can use tags in a similar fashion as using them in a Grafana query. When clicking + Add Tag, you can select only the data corresponding to that tag value. You can also use tags in the Group By row.

Styling

Customisation options

The colors of the following elements can be customised:

• Header 1
• Header 2
• Header 3
• Header 4
• Text color
• Table row background color

Example

This example should give you a better understanding of each customisable element in the styling section. The settings in this example are:

Setting	Color
Header 1	Blue
Header 2	Green
Header 3	Red
Header 4	Orange
Text color	Black
Table row background color	Grey

Preview

If you want to take a peek at how the report will look, you can click on "Preview"

Notifications

In this tab, you can select one or multiple team(s). When a new report is generated, it will send an email to every user of the selected team(s). You can add a team by selecting one in the select team tab. When clicking on the Bin Icon, the team will be removed.

On every generation, each member of the team(s) will receive an e-mail with the report attached:
