Live filtering of tables

General
Multiple measuring statistics show all entries in tables with different columns for all measured values, which can be sorted individually.
Since often there are a lot of entries, the Allegro Network Multimeter allows for filtering those tables to quickly find the relevant information.
All search text areas show a hint about for what kind of information the table can be filtered. Once entered, the table is updated immediately while still updating the measured values for the visible entries.
This live filtering allows for viewing live data only for the entries that are currently important for the investigation of a network problem.
Single word matching
It is always possible the enter a single word for filtering.
In this case the Allegro Network Multimeter will match any possible field for the given text.
For instance, in the IP statistics, the IP will be matched if a number representation is entered, with an optional subnet mask length (1.2.3.4/8).
The known alternative names are also matched, so it is possible to enter a host name and the list will show only those entries which contain the string in the DHCP name, DNS name, HTTP name, or any other name field.
Complex filter expressions
Some tables allow for using more complex expressions for flexible live filtering.
The support of filter expressions is indicated by the hint text in the search area, which informs that the entered string must start with an open parenthesis (.
In this mode it is possible to enter expressions in the form of keyword == value.
The keyword depends on the actual context of the search field, often name, ip, or packets is possible.
The web interface will give hints about all possible keywords in the current context which usually directly correlate with the available columns.
Also, the comparison operator can be == or != for equal or unequal compare, but for numbers <, >=, etc can be used too.
Multiple expressions can be combined with boolean operators and or or (or equivalent && / ||). Also, parentheses can be used to enter even more complex expressions.
Examples
- Show all IPs with at least 100 packets, that have been active within the last minute:
(packets > 100 and lasttime < 60)
- Show all IPs that showed up not more than 24 hours ago and have an associated name of alice or bob:
( (firsttime < 86400 and ( name == alice or name == bob ))- 86400 is the number of seconds in 24 hours (24 * 60 * 60)
Notes
- It is possible to enter values in quotes if they contain reserved characters used for the expressions (<,=,&,(, etc).
- Under the search text area, the interface will show all valid values for the last element entered in the expression.
- A green check mark indicates if the entered expression has been successfully parsed.

Wireshark filter syntax
Wireshark uses a filter syntax that is not directly compatible to the filter syntax in the Allegro Network Multimeter as it is more strict regarding the expression and also supports many packet header related fields.
However, Wireshark conversion filters for IPV4, IPV6, TCP, and UDP can be used directly:
- Example: The filter "(ip.addr eq 1.2.3.4 and ip.addr eq 2.3.4.5) and (tcp.port eq 80 and tcp.port eq 1234)" is a valid filter expression. The corresponding native expression is: "ip == 1.2.3.4 and ip == 2.3.4.5 and port == 80 and port == 1234 and l4protocol == TCP" (the last part about the l4protocol can be left out since most of the time there is only one connection matching the port portion).
