How To Verify Proper Zeek Operation

first, please note that Bro has been renamed to Zeek but the packages still adhere to the traditional bro naming convention
as the Zeek packages install, verify that the package installation scripts display a message about checking configuration and adding back any local customizations
verify that Bro packages were upgraded:
```
dpkg -l |grep securityonion-bro
```
verify that the new Zeek packages create symlinks as necessary so that the new zeek paths resolve to the traditional bro locations (for example: /opt/zeek is a symlink to /opt/bro, /nsm/zeek is a symlink to /nsm/bro, etc.)
verify that the new Zeek packages create symlinks as necessary so that well known bro files resolve to the new zeek locations (for example: /opt/bro/etc/broctl.cfg is a symlink to zeekctl.cfg, so it can be accessed via /opt/bro/etc/broctl.cfg or /opt/zeek/etc/zeekctl.cfg)
if new installation, run through Setup
verify that the package installation scripts backed up the following with a _pre-3.0.7 extension: /opt/bro/etc/ /opt/bro/share/bro/
verify that StatusCmdShowAll has been set to 0 in /opt/zeek/etc/zeekctl.cfg:
```
grep StatusCmdShowAll /opt/zeek/etc/zeekctl.cfg
```
verify that "lb_custom.InterfacePrefix=af_packet::" has been added to /opt/zeek/etc/zeekctl.cfg:
```
grep af_packet /opt/zeek/etc/zeekctl.cfg
```
Restart Zeek:
```
sudo so-zeek-restart
```
check status:
```
sudo so-status
```

check Zeek startup logs for any warnings/errors out of the ordinary:

cat /nsm/zeek/logs/current/reporter.log
cat /nsm/zeek/logs/current/stdout.log
cat /nsm/zeek/logs/current/stderr.log

replay LOTS of traffic:
```
sudo so-test
```
verify that files are extracted to /nsm/zeek/extracted:
```
ls -alh /nsm/zeek/extracted
```
verify that /nsm/zeek/logs/current/conn.log contains the proper sensorname at the end of each log entry:
```
cat /nsm/zeek/logs/current/conn.log
```
verify that Zeek logs are in the same format as they were pre-upgrade (should be JSON by default).
verify that the Elastic Stack is parsing and displaying Zeek logs properly (whether JSON or TSV format)
verify that you can pivot to CapMe for both TCP and UDP traffic
check sostat output for anything out of the ordinary (specifically, check the pf_ring and Zeek sections for packet loss)
verify that Zeek ja3 script is loaded and logging:
```
grep ja3 /nsm/zeek/logs/current/*
```
verify that Zeek hassh script is loaded and logging:
```
grep hassh /nsm/zeek/logs/current/*
```
verify that /etc/cron.d/bro has been moved to /etc/cron.d/zeek and that it works properly
verify that /opt/samples/zeek is a symlink to /opt/samples/bro
verify that everything else works properly with no regressions
reboot and make sure everything still works properly

Please test in as many different combinations as possible:
