Overview ¶
The diagnostics package contains different tools to collect data they can be executed using the following flags at the test suite
- `--collect-conntrack`: Call `conntrack -L` - `--collect-iptables`: Call `iptables -L -n` - `--collect-ovsflows`: Call `ovs-ofctl dump-flows` per interface - `--collect-tcpdump`: Call `tcpdump -vvv -nne` per interface and expression
To integratre them with new test first instance the diagnostics package with ¶
```golang fr = wrappedTestFramework("my-test-suite") d = diagnostics.New(fr) ```
Then at the beginning of test initialize conntrack, ovsflows and iptables like ¶
```golang
d.ConntrackDumpingDaemonSet()
d.OVSFlowsDumpingDaemonSet("breth0")
d.IPTablesDumpingDaemonSet()
```
And add tcpdump to the test place where the expression can be composed, for example to dump tcpdump related to a service nodeport, the expression will be composed after creating the service, also specifying the interfaces.
```golang
d.TCPDumpDaemonSet([]string{"any", "eth0", "breth0"}, fmt.Sprintf("port %s or port %s", port, nodePort))
```
