Netskope parser

The Netskope parser can parse Netskope log messages. These messages do not completely comply with the syslog RFCs, making them difficult to parse. The netskope-parser() of AxoSyslog solves this problem, and can separate these log messages to name-value pairs. For details on using value-pairs in AxoSyslog see Structuring macros, metadata, and other value-pairs. The parser can parse messages in the following format:


For example:

   <134>{"count": 1, "supporting_data": {"data_values": ["x.x.x.x", "[email protected]"], "data_type": "user"}, "organization_unit": "domain/domain/Domain Users/Enterprise Users", "severity_level": 2, "category": null, "timestamp": 1547421943, "_insertion_epoch_timestamp": 1547421943, "ccl": "unknown", "user": "[email protected]", "audit_log_event": "Login Successful", "ur_normalized": "[email protected]", "_id": "936289", "type": "admin_audit_logs", "appcategory": null}

If you find a message that the netskope-parser() cannot properly parse, contact us, so we can improve the parser.

The AxoSyslog application sets the ${PROGRAM} field to Netskope.

By default, the Netskope-specific fields are extracted into name-value pairs prefixed with .netskope. For example, the organization_unit in the previous message becomes ${.netskope.organization_unit}. You can change the prefix using the prefix option of the parser.


   @version: 4.8.0
    @include "scl.conf"
    log {
        source { network(flags(no-parse)); };
        parser { netskope-parser(); };
        destination { ... };

Note that you have to disable message parsing in the source using the flags(no-parse) option for the parser to work.

The netskope-parser() is actually a reusable configuration snippet configured to parse Netskope messages. For details on using or writing such configuration snippets, see Reusing configuration blocks. You can find the source of this configuration snippet on GitHub.



Description: Insert a prefix before the name part of the parsed name-value pairs to help further processing. For example:

  • To insert the my-parsed-data. prefix, use the prefix(my-parsed-data.) option.

  • To refer to a particular data that has a prefix, use the prefix in the name of the macro, for example, ${}.

  • If you forward the parsed messages using the IETF-syslog protocol, you can insert all the parsed data into the SDATA part of the message using the prefix( option.

Names starting with a dot (for example, .example) are reserved for use by AxoSyslog. If you use such a macro name as the name of a parsed value, it will attempt to replace the original value of the macro (note that only soft macros can be overwritten, see Hard versus soft macros for details). To avoid such problems, use a prefix when naming the parsed values, for example, prefix(my-parsed-data.)

By default, netskope-parser() uses the .netskope. prefix. To modify it, use the following format:
