Session statistics

The api/audit/sessions/stats endpoint provides statistics about recorded sessions (active and closed).

URL
GET https://<IP-address-of-SPS>/api/audit/sessions/stats?field=<field-name>
Cookies
Cookie name Description Required Values
session_id Contains the authentication token of the user Required

The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the SPS REST API.

Note that this session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format).

Sample request

The following command retrieves statistical data about sessions.

curl --cookie cookies https://<IP-address-of-SPS>/api/audit/sessions/stats?field=<field-name>
Request parameters

Use the following parameters to fine-tune your request for statistics:

  • ?q: Narrow down the scope of statistics using one or more properties (elements) of the sessions.

  • ?field: Request statistics for the selected properties (elements and values) of sessions (for example, protocol).

    Using this parameter is mandatory.

  • ?sub_fields: Request sub statistics for the selected properties (elements and values) of sessions (for example, protocol).

    This parameter only accepts a single parameter. If more than one parameter is listed, only the first will be considered.

  • ?size: Limit the range of values displayed in the statistics for a given field. Statistics will be shown only for the top size number of most frequently occurring values (that is, values with the highest number of counts).

    Take the following example. If you query "/api/audit/sessions/stats?field=protocol&size=2", and the following sessions were recorded:

    ...
    {
      "Alpha": {
        "protocol": "http"
      },
      "Bravo": {
        "protocol": "ssh"
      },
      "Charlie": {
        "protocol": "rdp"
      },
      "Delta": {
        "protocol": "rdp"
      },
      "Echo": {
        "protocol": "rdp"
      },
      "Foxtrot": {
        "protocol": "http"
      },
      "Golf": {
        "protocol": "http"
      }
    }
    ...

    The response contains:

    ...
    {
     "meta": {
        "href": "/api/audit/sessions/stats",
        "parent": "/api/audit/sessions",
        "others": 1,
        "field": "protocol",
        "size": 2
     }
    }
    ...

    And the response items look like the snippet below. That is, in this example, there will be no statistics for "protocol": "ssh". The top 2 values are "rdp" and "http", with a count of 3 each. "ssh" occurred only once, so it did not make it to the top 2 most frequent values.

    ...
    [
     {"count": 3, "value": "http"},
     {"count": 3, "value": "rdp"}
    ...
  • ?start: Statistics are returned for sessions that started after the specified date. Use the ISO 8601 format for the date, for example, 2017-01-25T10:00.

  • ?end: Statistics are returned for sessions that ended before the specified date. Use the ISO 8601 format for the date, for example, 2017-01-25T11:00.

  • ?content: Statistics are returned for indexed sessions that contain the type of content specified.

    NOTE:

    When performing a content query, the maximum number of results returned is 3000. When this limit is exceeded, the scope of statistics is limited to the first 3000 sessions (even if there are more than 3000 sessions that match your criteria).

Response

The following snippet is a sample response received when retrieving statistics about the protocol field.

For details of the meta object, see Message format.

Those fields of the meta object that are specific to statistics are collected in table Element .

{
    "items": [
        {
            "count": 7,
            "value": "ssh"

    ],
    "meta": {
        "field": "protocol",
        "href": "/api/audit/sessions/stats",
        "others": 0,
        "parent": "/api/audit/sessions",
        "remaining_seconds": 600,
        "size": 10
    }
}
Element Type Description
body, or items when a list is returned Top-level element (string) Contains the properties that are in the scope of the requested statistics.
count integer Indicates the number of sessions included in the scope of statistics.
value string Contains the value of the field that you requested statistics about.
meta Top-level element Contains links to different parts of the REST service.
field string Contains the name of the field that you requested statistics about.

Session histogram

The api/audit/sessions/histogram endpoint provides a histogram about the recorded sessions.

URL
GET https://<IP-address-of-SPS>/api/audit/sessions/histogram
Cookies
Cookie name Description Required Values
session_id Contains the authentication token of the user Required

The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the SPS REST API.

Note that this session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format).

Sample request

The following command retrieves statistical data about sessions.

curl --cookie cookies https://<IP-address-of-SPS>/api/audit/sessions/histogram
Request parameters

Use the following parameters to fine-tune your request for statistics:

  • ?q: Narrow down the scope of the histogram using one or more properties (elements) of the sessions.

  • ?field: Create a histogram for the selected properties (elements and values) of sessions (for example, protocol).

    Using this parameter is mandatory.

  • ?bin-size: Determines the size of the unit for the histogram, for example, hour. SPS splits the queried period to intervals of this unit, and returns the number of sessions to each interval. For example, if you query an histogram from 2018-02-12:14:40 to 2018-02-16:14:40, and you set the bin-size to day, then SPS will return five datasets (one for each day). If you set the bin-size to week, then SPS will return only one dataset.

  • ?start: Create a histogram from the sessions that started after the specified date. Use the ISO 8601 format for the date, for example, 2017-01-25T10:00. By default, this is the one month before the date of the request.

  • ?end: Create a histogram from the sessions that ended before the specified date. Use the ISO 8601 format for the date, for example, 2017-01-25T11:00. By default, this is the date of the request.

  • ?size: Limit the range of values displayed in the histogram for a given field. The histogram will only be created for the top size number of most frequently occurring values (that is, values with the highest number of counts).

Response

The following snippet is a sample response received when retrieving a histogram about the audited sessions.

Element Type Description
items list Top level element, a list containing the alerts of the session.
alert_type string

The type of the event that triggered the alert. Possible values:

  • adp.event.command: A command entered in SSH or Telnet.

  • adp.event.screen.content: Alert triggered by the screen content.

  • adp.event.screen.creditcard: Credit card numbers detected. Displayed only as an alert, not visible in the events.

  • adp.event.screen.windowtitle: The title of the window in graphic protocols.

channel_id string The regular expression that matched the command line without prompt.
matched_action integer A reference to the ID of the channel in the session where the event occurred.
matched_content text The content that occurred in the session and triggered the alert. Note that this value contains the context of the match as well. For example, if a Content Policy triggers an alert if a user types the sudo command, then the psm.alerts.matched_content value contains the entire command line, including the command prompt, for example, myuser@examplehost:~$ man sudo
matched_regexp text The regular expression (match field) of the Content Policy that matched a part of the content and triggered the alert. For details, see Real-time content monitoring with Content Policies.
record_id integer The ID number of the alert within the session.
rule_name string The name of the content policy rule that triggered the alert. Note that this is not the name of the Content Policy.
time string The timestamp when the alert was triggered, for example, 2017-04-25T13:26:39.144356.
Changing the display limit

You can use the ?limit option to change the number of items displayed at once. The default limit is 500.

?limit=1000

To navigate beyond the displayed set, use the offset option.

Navigating large datasets

You can use the ?offset option to navigate data sets that extend beyond the display limit. The default value of the offset is 0, this is the initially displayed set. To move to other items beyond the initial set, increase the value to a number that corresponds to the item where you want to start displaying results from.

Example: the display limit is the default 500, and the number of sessions is 1012. The initial 500 sessions are listed at:

?offset=0

To view sessions from 501 to 1000, change the offset to 501:

?offset=501

To display the remaining 12 sessions, change the offset to 1001:

?offset=1001
Sorting and filtering

Sorting and filtering alerts is currently not supported. The items are automatically sorted by the record ID. The response includes every available field.

Session events

The api/audit/sessions/<session-id>/events endpoint lists the events extracted from a session (if any). Events are available only if the session is indexed. For details on configuring indexing, see Local services: configuring the indexer.

URL
GET https://<IP-address-of-SPS>/api/audit/sessions/<session-id>/events

Element Type Description
items list Top level element, a list containing the alerts of the session.
action string The command line without prompt in commands.
channels_id integer A reference to the ID of the channel in the session where the event occurred.
content text The event that occurred in the session. Note that this value contains the context of the event as well. For example, for command events in terminal sessions, the value contains the entire command line, including the command prompt. For example, myuser@examplehost:~$ man sudo
record_id integer The ID number of the event within the session.
type string

The type of the event. Possible values:

  • command: A command entered in SSH or Telnet.

  • file_transfer: A file transfer event.

  • http_request: An HTTP request initiated during the session.

  • window_title: The title of the window in graphic protocols.

time string The timestamp when the event occurred, for example, 2017-04-25T13:26:39.144356.
Changing the display limit

You can use the ?limit option to change the number of items displayed at once. The default limit is 500.

?limit=1000

To navigate beyond the displayed set, use the offset option.

Navigating large datasets

You can use the ?offset option to navigate data sets that extend beyond the display limit. The default value of the offset is 0, this is the initially displayed set. To move to other items beyond the initial set, increase the value to a number that corresponds to the item where you want to start displaying results from.

Example: the display limit is the default 500, and the number of sessions is 1012. The initial 500 sessions are listed at:

?offset=0

To view sessions from 501 to 1000, change the offset to 501:

?offset=501

To display the remaining 12 sessions, change the offset to 1001:

?offset=1001
Filtering

You can filter events at the /api/audit/sessions/<session-id>/events endpoint. Use the ?q option to filter the list using one or more properties (elements) of the sessions.

?q=content:sudo

You can escape special characters using the backslash character.

?q=content:\"Copying Files\"

To add multiple elements to the filter, you can use the AND, AND NOT, and OR operators.

content:ls AND content:cp AND NOT content:mv

You can create groups using () (parentheses).

?q=(content:rm OR content:mv) AND channels_id:5

You can also use () (parentheses) to add multiple possible values for a property.

?q=content:(sudo rm)

You can use the * (asterisk) and ? (question mark) wildcards for string-type values.

?q=content:?dmi*

You can define ranges using [] (brackets) or {} (braces) and the TO operator. This only works for numeric (int) values.

  • [ means equal or higher than the following value

  • ] means equal or lower than the preceding value

  • { means higher than the following value

  • }means lower than the preceding value

For example, the following range resolves to 2:

?q=channels_id:{1 TO 3}

You can also use the * (asterisk) wildcard in the range.

?q=channels_id:[* TO 5]

Note that not all connection data can be used for filtering. The available elements are:

  • channels_id

    Integer, the channel in the session where the event occurred.

  • content

    Text, the event that occurred in the session.

  • record_id

    Integer, the identifier of the event in the session.

  • time

    String, the timestamp when the event occurred.

  • type

    String, the type of the event:

    • command: A command entered in SSH or Telnet.

    • screen.content: Screen content.

    • screen.creditcard: Credit card numbers detected. Displayed only as an alert, not visible in the events.

    • screen.windowtitle: The title of the window in graphic protocols.
