Select a parameter matching method from the Parameter Match list and specify details for up to four parameters.

The following matching methods are supported:

Exact

Report the specified parameter or the parameter and value.

Usage syntax

'name=value' or just 'name'. Source

By selecting the appropriate check box, you can cause the parameter to be searched for in the request URL, POST body, or HTTP header.

If more than one option is selected, the selected parameter sources are searched for in sequence, in the order specified for HTTP analysis, until the first match is found.

Method of matching parameters

Parameters are identified in the request URL, POST body, or HTTP header by searching for the appropriate separator characters, as defined for the analysis of HTTP. After individual parameters have been identified a match is attempted for each parameter.

Limitations

A case-insensitive match is performed; no wildcard characters are permitted in Chapter 7 ∙ Configuring AMD to Monitor User-Defined Software Services

Combining parameters

If you have defined more than one parameter for a given URL, for a match to be successful all specified parameters have to be matched. When all matches are found, the reported string then contains a concatenation of all the matched parameters, separated by the ampersand “&” character.

Note that for a single URL, different parameters can be extracted from different portion of the HTTP packet, request URL, POST body, or HTTP header, and combined into a single match.

Examples

You can specify 'john', to match http://host.com/page?john, though

note that in this case http://host.com/page?john=123 will not be reported

because the parameter value '=123' was not explicitly specified. To match it,

you would need to specify 'john=123'. Start

Report parameters that begin with a specified string; report only the matched pattern, truncate any remainder of the parameter.

Usage syntax

'name=value' or any initial part of it this string, including string of the form 'name=' or just 'name'.

Source

By selecting the appropriate check box, you can cause the parameter to be searched for in the request URL, POST body, or HTTP header.

If more than one option is selected, the selected parameter sources are searched for in sequence, in the order specified for HTTP analysis, until the first match is found.

Method of matching parameters

Limitations

A case-insensitive match is performed; no wildcard characters are permitted in the string.

Combining parameters

Note that for a single URL, different parameters can be extracted from different portion of the HTTP packet, request URL, POST body, or HTTP header, and combined into a single match.

Examples

'fred=5' will match http://host.com/page?fred=500ab but it will be

reported as http://host.com/page?fred=5. The value 'fred' will match Chapter 7 ∙ Configuring AMD to Monitor User-Defined Software Services

http://host.com/page?fred=500ab as well as http://host.com/page?fred and it will be reported as

http://host.com/page?fred. Start (expand)

Report parameters which begin with a specified string; report the entire parameter, not only the matched pattern.

Usage syntax

'name=value' or any initial part of it this string, including string of the form

'name=' or just 'name'. Source

By selecting the appropriate check box, you can cause the parameter to be searched for in the request URL, POST body, or HTTP header.

Note that more than one option can be selected, and in such a case, the selected parameter sources are searched for in sequence, in the order specified for HTTP analysis, until the first match is found.

Method of matching parameters

Parameters are identified in the request URL, POST body, or HTTP header by searching for the appropriate separator characters, as defined for the analysis of HTTP. After individual parameters have been identified a match is attempted for each parameter.

Limitations

A case-insensitive match is performed; no wildcard characters are permitted in the string.

Combining parameters

Note that for a single URL, different parameters can be extracted from different portion of the HTTP packet, request URL, POST body, or HTTP header, and combined into a single match.

Decoding and decompression

The string to match the regular expression is first optionally decoded and decompressed, if the appropriate encoding and compression is selected.

Examples

'fred=5' will match http://host.com/page?fred=500ab and it will be

reported as http://host.com/page?fred=500ab. The value 'fred' will match http://host.com/page?fred=500ab as well as

http://host.com/page?fred and it will be reported as

http://host.com/page?fred=500ab and http://host.com/page?fred

respectively.

Usage syntax

'name=value' or any final part of it this string, including string of the form '=value' or just 'value'.

Source

By selecting the appropriate check box, you can cause the parameter to be searched for in the request URL, POST body, or HTTP header. Note that more than one option can be selected, and in such a case, the selected parameter sources are searched for in sequence, in the order specified for HTTP analysis, until the first match is found.

Method of matching parameters

Parameters are identified in the request URL, POST body, or HTTP header by searching for the appropriate separator characters, as defined for the analysis of HTTP. After individual parameters have been identified a match is attempted for each parameter.

Limitations

A case-insensitive match is performed; no wildcard characters are permitted in the string.

Note that for a single URL, different parameters can be extracted from different portion of the HTTP packet, request URL, POST body, or HTTP header, and combined into a single match.

Examples

For http://host.com/page?john=100' to be matched, you can specify the

following ends: '0', '00', '100', '=100', 'n=100' and so on, up to 'john=100'. Thus http://host.com/page?john=100 is reported. Value RegEx

Report parameters which begin with a specified string; optionally attempt to match the remainder of the parameter with a regular expression; report the start string and selected portions of the regular expression, if any.

Usage syntax

Parameter is entered as name=value or any initial part of it this string including

string of the form name= or just name. A regular expression (regex) is entered

as an extended POSIX regular expression.

Source

By selecting the appropriate check box, you can cause the parameter to be searched for in the request URL, POST body, or HTTP header.

Note that more than one option can be selected, and in such a case, the selected parameter sources are searched for in sequence, in the order specified for HTTP analysis, until the first match is found.

Method of matching parameters

Parameters are identified in the request URL, POST body, or HTTP header by searching for the appropriate separator characters, as defined for the analysis of HTTP. After individual parameters have been identified a match is attempted for each parameter.

Limitations

A case-insensitive match is performed on the Parameter part; the regex part is matched as a case-sensitive POSIX regular expression.

Combining parameters

If you have defined more than one parameter for a given URL, for a match to be successful all specified parameters have to be matched. When all matches are found, the reported string then contains a concatenation of all the matched parameters, separated by the ampersand “&” character.

Note that for a single URL, different parameters can be extracted from different portion of the HTTP packet, request URL, POST body, or HTTP header, and combined into a single match.

Decoding and decompression

The string to match the regular expression is first optionally decoded and decompressed, if the appropriate encoding and compression is selected.

Examples

parameter specification fred= and a regular expression AB(C?E) will match http://host.com/page/fred=ABCDE but it will be reported as

http://host.com/page/fred=CDE because the AB portion of the regular

expression was not included in round braces.

Custom RegEx

Report parameters that match the given regular expression; report those portions that have been selected within the regular expression.

Usage syntax

Enter an extended POSIX regular expression to match the desired string. Mark portions to be reported by using round braces “(” and “)”.

Source

By selecting the appropriate check box, you can cause the parameter to be searched for in the request URL, POST body, or HTTP header.

Note that more than one option can be selected, and in such a case, the selected parameter sources are searched for in sequence, in the order specified for HTTP analysis, until the first match is found.

Method of matching parameters

The request URL, POST body, or HTTP header are not split into parameters prior to pattern matching. Instead, they are treated as single units of data and the regular expression is applied to their entire contents. Only the path part of the request URL is excluded from the matching process.

Limitations

Combining parameters

If you have defined more than one parameter for a given URL, for a match to be successful all specified parameters have to be matched. When all matches are found, the reported string then contains a concatenation of all the matched parameters, separated by the ampersand “&” character.

Note that for a single URL, different parameters can be extracted from different portion of the HTTP packet, request URL, POST body, or HTTP header, and combined into a single match.

Decoding and decompression

The string to match the regular expression is first optionally decoded and decompressed, if the appropriate encoding and compression is selected.

Examples

Regular expression fred=AB(C?E) will match

http://host.com/page/fred=ABCDE but it will be reported as

http://host.com/page/CDE.

Regular expression (.*=)AB(C?E) will match http://host.com/page/fred=ABCDE as well as

http://host.com/page/joe=ABCDE and it will be reported as

http://host.com/page/fred=CDE and as http://host.com/page/joe=CDE

respectively.
