PRTG Manual: Multiple Object Property or Status

<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Multiple Object Property or Status

You can access live data and live status data of multiple objects using the PRTG API.

Authentication with user name and passhash (or user name and password) must always be included in each PRTG API request. See section HTTP API for more information.

In this section:

Property or Status of Multiple Objects

Most data that you can request from the PRTG API is available in data tables in the Extensible Markup Language (XML) format, the JavaScript Object Notation (JSON) format, and the comma-separated values (CSV) format (using the XML format is recommended). The API function /api/table.xml is used to access data in tables. Here are some sample calls (URLs are shown without authentication parameters to enhance readability).

The example URLs only show the XML URLs. Use the API function /api/table.csv or the output=constable parameter to select the CSV format, or /api/table.json to return the JSON format.

Examples

A hierarchical list of all groups, devices, and sensors with their status information:

/api/table.xml?content=sensortree

sensortree does not support JSON output.

All sensors (with status information):

/api/table.xml?content=sensors&columns=objid,group,device,sensor,status,message,lastvalue,priority,favorite

All recent log entries:

/api/table.xml?content=messages&columns=objid,datetime,parent,type,name,status,message

You have the easiest start if you use the table query builder or click , which most data tables have in the PRTG web interface. Navigate to the information that you want to use, click , and you are taken to a URL that renders the content of the table in XML format. You can now use the URL as it is or change various parameters to suit your needs.

For more information on possible raw message status values returned by table-based API calls, see the Knowledge Base: Is there a list of log status values for the PRTG API?

Table Query Builder

You can use the query builder tool to experiment with the PRTG API and to fine-tune your queries. You can find it in the PRTG web interface under Setup | PRTG API, section Live Data.

Output Data Format

XML data from the PRTG API contains the fields that you requested in the columns parameter. In most cases, numeric values are included twice: One field contains the value in human-readable format and an additional _RAW field contains the value as a number, which is better suited for further processing and calculations.

Example

<status>Up</status>
<status_RAW>3</status_RAW>
<lastvalue>98 %</lastvalue>
<lastvalue_RAW>97.7583</lastvalue_RAW>
<message>Created.<br/>18.3.43.1360</message>
<message_RAW>Created. 18.3.43.1360</message_RAW>

The status field shows the value Up (the according RAW value is 3).
The lastvalue field shows the value 98% (the according RAW value is 97.7583).
The message field shows the text Created.<br/>18.3.43.1360 (the according RAW value is Created. 18.3.43.1360).

Strings returned from _RAW columns are surrounded by double quotes (") in JSON output.

RAW Date/Time Format

For columns with date/time value, the RAW value is defined as follows: The integral part of a value is the number of days that have passed since Dec 30th, 1899. The fractional part of a value is a fraction of a 24-hour day that has elapsed. To find the fractional number of days between two dates, subtract the two values. Similarly, to increment a date and time value by a certain fractional number of days, add the fractional number to the date and time value.

Here are some examples of date/time RAW values and their corresponding dates and times:

RAW Date/Time Value	Description
0	12/30/1899 00h00m (12:00 midnight)
2.75	1/1/1900 18h00m (6:00 pm)
35065	1/1/1996 00h00m (12:00 midnight)

Common Data Table Parameters

The following parameters are common to all data table API calls:

Parameter	Description	Possible Values
content	Select the objects that you want to have in your table.	sensortree (JSON output not supported) devices sensors tickets ticketdata messages values channels reports storedreports toplists sysinfo (only JSON output supported)
columns	Comma-separated list of columns per record	see Supported Output Columns ("columns=" Parameter)
output	Control the output format	xml: default format (recommended) xmltable: an HTML table in the XML format csvtable: CSV format html: HTML table json: JSON format jsontable: a table in the JSON format
count	Maximum number of items (The default count is 500)	1-50000
start	Start with this entry number (can be used with "count" to request the data page by page)	any

Filtering by Object ID

Add an ID parameter (for example, id=1) to the API URL to select a subset of items for the data table, for example, to reduce the amount of data transferred for each data table API call. The data table only contains information for this object ID and its child objects.

Some table types require an ID. If you omit the ID parameter or if it has the value zero (0), all available objects are used.

Table Type (content=)	ID Required or Optional	Description	Object Types Allowed for the ID
sensortree	optional	You only get a part of the tree (the object with the specified ID and all child objects below it). JSON output is not supported.	Probe Group
sensors devices	optional	You only get the object with the specified ID and all child objects below it.	Probe Group Device
tickets messages	optional	You only get tickets or log file entries that are related to the object with the specified ID or any child objects below it.	Any object
values channels	required	You get the data values (or channels) of the sensor with the specified ID.	Sensor
reports	not used	This data table always includes all reports.	n/a
storedreports	required	You get a list of stored .pdf files of the report selected by the ID.	Report
ticketdata	required	You get the history of the ticket selected by the ID.	Ticket
sysinfo	required	You get system information of the object with the specified ID.	Device

Sorting and Advanced Filtering

There are various options to further filter and to sort the data for each data table API call:

Parameter	Description	Possible Values
filter_drel	Only include records younger than this setting For content=messages and content=tickets only.	today yesterday 7days 30days 12months 6months
filter_status	Only include sensors with a specific status. Using multiple filter_status fields performs a logical OR. For content=sensors only.	Unknown=1 Collecting=2 Up=3 Warning=4 Down=5 NoProbe=6 PausedbyUser=7 PausedbyDependency=8 PausedbySchedule=9 Unusual=10 PausedbyLicense=11 PausedUntil=12 DownAcknowledged=13 DownPartial=14
filter_tags	Only include sensors with a specific tag. Using multiple filter_tag fields performs a logical OR. For content=sensors only.	@tag(tagname)
filter_xyz	Filter the data. (Samples: filter_type=ping, filter_favorite=1). Using multiple filter_xyz fields performs a logical OR. Filtering using columns is only possible for tree objects. You cannot use columns to filter objects like messages or tickets, for example. For content=tickets, you can use the special filter terms filter_status filter_user, and filter_type (this corresponds to column tickettype). Like for messages, you can also use filter_drel, filter_dstart, and filter_dend. Multiple filters are not available for tickets.	filter_xyz where xyz is any column name used in the columns parameter Substrings: use filter_xyz=@sub(substring1,substring2) Values not equal/above/below: use filter_xyz=@neq(value), filter_xyz=@above(value), filter_xyz=@below(value)
sortby	Sort the data. If this parameter is omitted, the table is sorted based on the first column. Add a leading "-" to reverse sort order. (Samples: sortby=name, sortby=lastvalue, sortby=-lastvalue, sortby=uptime)	Any column name used in the columns parameter. Log tables with content=messages are always sorted by descending date.

Examples

Here are some samples for filtered API calls:

All sensors that are not in the Up status (with their status and downtime information):

/api/table.xml?content=sensors&columns=objid,downtimesince,device,sensor,lastvalue,status,message,priority
&filter_status=5&filter_status=4&filter_status=10&filter_status=13&filter_status=14&sortby=priority

Fastest Ping sensors:

/api/table.xml?content=sensors&columns=objid,sensor,lastvalue,status,message&sortby=lastvalue
&filter_type=ping

Log entries of the last 7 days for object id 2003:

/api/table.xml?content=messages&id=2003&start=0&filter_drel=7days&columns=
objid,datetime,type,name,status,message
