----------------------------------
Summary: topic/jazoff/broctld
Key: BIT-1320
URL: https://bro-tracker.atlassian.net/browse/BIT-1320
Project: Bro Issue Tracker
Issue Type: Problem
Components: BroControl
Reporter: Daniel Thayer
Fix For: 2.4
Branch topic/jazoff/broctld in the broctl repo contains significant code
reorganization
for the upcoming broctld. Here is a high-level list of changes:
1) Refactor broctl to make it usable as a library (reduce global state,
module-level setup code, and functions return results instead of printing),
2) Integrate ssh_runner code into broctl to fix current problems (use only one
connection per host instead of one per Bro node, broctl shouldn't hang when a
host goes down or if we forgot to run "broctl install"),
3) Write state info using SQLite state storage instead of writing to a plain
text file (broctl.dat),
4) When the node config changes, we now do additional checks if there are any
Bro nodes running that are no longer in our node config and warn user if any
are detected,
5) Keep track of the expected state (running or stopped) of each Bro node, and
have broctl cron start or stop nodes as needed,
6) Improved broctl cron by adding two new options (MailHostUpDown and
StatsLogEnable) to enable users the option to turn off unwanted functionality
to speed up broctl cron and reduce the chance of errors,
7) When broctl cron tries to send email but fails, now it will output a message
that includes the text it was trying to mail,
8) Silence warning messages (that are intended for interactive use of broctl)
when broctl cron runs to reduce unwanted emails from cron,
9) Added new broctl option StatusCmdShowAll to enable users to speed up "broctl
status" significantly,
10) Fixed the stats-to-csv script to not create files that can never include
any data,
11) Fixed archive-log script to detect exit status of gzip or cp command, so
that we don't delete log file when the archival fails,
12) Improved post-terminate script to process log files more consistently,
13) Made all broctl command output go to stdout (previously, some output would
go to stderr, which made grepping or redirecting the output more difficult),
14) Improved the default broctl.cfg file to show more of the useful options,
15) Added more error checks to help catch errors earlier,
16) Some error message output is more specific and helpful now
