Fedora default traffic monitor tool

Ping packets should use an ICMP type of 8 (echo) or 0 (echo reply), so you could use a capture filter of:

icmp

and a display filter of:

icmp.type == 8 || icmp.type == 0

For HTTP, you can use a capture filter of:

tcp port 80

or a display filter of:

tcp.port == 80

or:

http

Note that a filter of http is not equivalent to the other two, which will include handshake and termination packets.

If you want to measure the number of connections rather than the amount of data, you can limit the capture or display filters to one side of the communication. For example, to capture only packets sent to port 80, use:

dst tcp port 80 

Couple that with an http display filter, or use:

tcp.dstport == 80 && http

For more on capture filters, read "Filtering while capturing" from the Wireshark user guide, the capture filters page on the Wireshark wiki, or pcap-filter (7) man page. For display filters, try the display filters page on the Wireshark wiki. The "Filter Expression" dialog box can help you build display filters.

I'm gong to echo, for the most part, the answer JMurphy provided. Wireshark (IMO) doesn't lend itself very well to the type of analysis you're looking to do. Wireshark is better suited to detailed traffic analysis when you're trying to solve a specific network problem between two hosts.

What I would suggest would be one of two things:

1. PRTG or MRTG. This can give you a high level overview of the traffic transiting your internet connection, such as traffic type (HTTP, SMTP, etc.) and the hosts involved in said traffic (source and destination) as well as being able to give you traffic summaries, such as the volume of HTTP traffic, etc.

2. NetFlow or its alternative, depending on what your router and/or switches support. Again, this can give you a high level overview of the traffic transiting your internet connection, such as traffic type (HTTP, SMTP, etc.) and the hosts involved in said traffic (source and destination) as well as being able to give you traffic summaries, such as the volume of HTTP traffic, etc.
