Posted: Fri Feb 27, 2009 12:27 am Post subject: TIP: Send SMS alerts when emerge completes |
|
|
My most recent large update (>500 packages) prompted this idea. Around the tenth time an ebuild failed mere moments after I left the room (not to return for hours), I decided to have the darn thing alert me when it wanted attention.
The following assumes you have installed:- The mailx client (mail-client/mailx), to send mail from shell scripts and the command line.
- An MTA (mail transfer agent) for mailx to use, such as Postfix, Sendmail or ssmtp.
This script is intended to run in a pipeline after emerge and send a short message to explain why emerge stopped. /usr/local/sbin/emobalert: | #!/bin/sh
# Record exit status of emerge--must precede ALL other commands!
[ $? -eq 0 ] && RESULT="PASS" || RESULT="FAIL"
# Change next line to your mobile/SMS address
SMS_ADDR="2015551212@sms.some-mobile.com"
LAST_PKG="$(tac /var/log/emerge.log | awk '$2 == ">>>" {print $4,$5,$6,$7; exit;}')"
CFG_MODS="$(find /etc -iname '._cfg????_*' | wc -l)"
mail -s"Emerge Completed" $SMS_ADDR <<-EOM
${RESULT} ${LAST_PKG}
:::
${CFG_MODS} config updates pending
$*
EOM | Change SMS_ADDR to your phone's SMS address and be sure to mark the script executable. You might also want to make it readable only by root if you need to guard your mobile number.
Usage is simple: Example: | emerge -uDv world; emobalert | That's it. Notice you run the script unconditionally after emerge so it can detect the exit status (that is, use the semicolon, never && or || or any other pipe connector).
When emerge exits, you'll receive a text message similar to this: Sample message: | From: root@localhost.localdomain
(Emerge Completed)
PASS (2 of 2) app-crypt/seahorse-2.22.3
:::
0 config updates pending | The message body reports the last ebuild attempted, whether the overall merge succeeded or failed and whether you need to apply any configuration file updates. Any command-line arguments supplied to emobalert are appended to the message.
On those rare occasions when you have better things to do than watch compiler output scroll by, this trick helps you still catch problems quickly. _________________ Plants are pithy, brooks tend to babble--I'm content to lie between them.

Very nice. Thank you for sharing it.
I had thought about dropping a .forward file with my sms address during emerges, but even with "email_summary", it's far too much data. This captures the important tidbits. |

For US Verizon Wireless numbers the gateway address is number@vtext.com for text, number@vzwpix.com for multimedia messages. I think most carriers provide a similar service (in the US at least). Check the support section of the carrier's website or call customer service. _________________ Plants are pithy, brooks tend to babble--I'm content to lie between them.

You might want to only send a few until you get a bill, so you can make sure they're not charging you (or see how much they're charging you). |

True... Though, if I understand the script well, it seems that the informative value of running it after emerge -keep-going would be very small. Did you think about modifying it so that it would parse the log more thoroughly? I guess it wouldn't be that difficult to detect, how many packages were skipped during such emerge job. |

I am not too fond of --keep-going, I prefer to fix problems as they arise (as you might have guessed ). When I have some time I'll look into counting failed packages. I have an idea for a simple solution but need to experiment.

This is one of the coolest things I have ever seen someone contribute! I really would like to see this suggested as a feature update to portage so that you can just define an address in your /etc/make.conf and have it done every time without remembering to run the script. Have you submitted it as a feature request? I'd certainly vote for it's injection!!
Awesome work! Thanks so much for sharing!! _________________

Hey this looks like a great little script. Thanks so much for your effort.
I was wondering if this could be edited to include the ability to send an email about a package failure. I do have a cell phone but I'm a cheap sob and don't have unlimited text. _________________ Increasingly becoming a 2 channel audio nut! |

Sure you can. I've made some quick and ugly (and it is *ugly*) hack some days ago to send also latest logfile path (this could be edited to send ie. tail -100 failed.log).
Code: | #!/bin/sh
# Record exit status of emerge--must precede ALL other commands!
[ $? -eq 0 ] && RESULT="PASS" || RESULT="FAIL"
# Change next line to your mobile/SMS address
SMS_ADDR="your@mail"
LAST_PKG="$(tac /var/log/emerge.log | awk '$2 == ">>>" {print $4,$5,$6,$7; exit;}')"
CFG_MODS="$(find /etc -iname '._cfg????_*' | wc -l)"
LOG_PKG="$(ls -l -rt /var/log/portage/ | grep -v elog | tail -1 | awk '{print $9}')"
mail -s"Emerge Completed" $SMS_ADDR <<-EOM
${RESULT} ${LAST_PKG}
:::
see latest logfile /var/log/portage/${LOG_PKG}
$*
EOM

I'll look into it soon and either find a more reliable test or file a bug on Portage (if warranted). _________________ Plants are pithy, brooks tend to babble--I'm content to lie between them.

I realize this is a bit late but in my frustration with waiting for undefined amounts of time led me to make a similar script "run_with_email_confirm" (a bit of a mouthful i know heh).
Code: | #!/bin/bash
if [ $# -lt 1 ]; then
echo "Usage: $0 <COMMANDS>"
exit 1;
fi
OUTPUT_TEMP_FILE=/etc/output.log
echo RUNNING:
count=1
for arg in "$@"; do
echo "#${count}: ${arg}"
done
for arg in "$@"; do
$arg | tee ${OUTPUT_TEMP_FILE}
EXIT_STATUS=${PIPESTATUS[0]}
if [ $EXIT_STATUS -ne 0 ] ; then
COMMAND="${arg}"
RESULT=$EXIT_STATUS
OUTPUT=$(tail -n 30 "${OUTPUT_TEMP_FILE}")
echo "EXIT STATUS: ${EXIT_STATUS}"
email_results "${COMMAND}" "${RESULT}" "${OUTPUT}"
rm "${OUTPUT_TEMP_FILE}"
exit ${EXIT_STATUS}
else
echo "EXIT STATUS: ${EXIT_STATUS}"
fi
done
email_results "${FULL_COMMAND}" 0
rm "${OUTPUT_TEMP_FILE}"
exit 0
|
If you read through the script closely you'll notice that I'm both printing to the console and saving STDOUT and STDERR to a log file.
The script basically does this:
Code: | run_with_email_confirm "emerge --sync" "emerge -u world" |
separate the commands (each of which is just an argument)
run them one at a time
if it passes then run the next command (if it passes all command arguments, then send an email with a PASS and indicate the commands run)
if it fails then take the command that failed ${arg}, exit code ${PIPESTATUS[0]}, last 30 lines of console output ${OUTPUT_TEMP_FILE} and pass it to the email script "email_results" which basically makes it pretty.
The script "email results"[/list] is as follows:
Code: |
#!/bin/bash
if [ $# -lt 2 ] || [ $# -gt 3 ]; then
echo "Usage: $0 <COMMAND> <RESULT> <OUTPUT: optional>"
exit 1;
fi
EMAIL="<your email goes here>"
COMMAND=$1
EXIT_STATUS=$2
if [ $2 -eq 0 ]; then
RESULT="PASS"
else
RESULT="FAIL"
fi
OUTPUT=$3
{
echo "<table>"
echo "<tr>"
echo "<td width=\"100\"><b>DEVICE</td><td>: </td></b> <td>$HOSTNAME</td>"
echo "</tr>"
echo "<tr>"
echo "<td width=\"100\"><b>COMMAND</td><td>: </td></b> <td>$COMMAND<br></td>"
echo "</tr>"
if [ $EXIT_STATUS == 0 ]; then
echo "<tr>"
echo "<td width=\"100\"><b>RESULT</td><td>: </td></b> <td>PASS</td>"
echo "</tr>"
echo "</table>"
else
echo "<tr>"
echo "<td width=\"100\"><b>RESULT</td><td>: </td></b> <td>FAIL</td>"
echo "</tr>"
echo "<tr>"
echo "<td width=\"100\"><b>CODE</td><td>: </td></b> <td>$EXIT_STATUS</td>"
echo "</tr>"
echo "</table><br>"
echo -e "<td><b>OUTPUT:</b><br><br>"
echo "$OUTPUT<br>"
fi
} | mutt -e "set content_type=text/html" -s "$HOSTNAME: $RESULT notification" $EMAIL
|
I apologize for all the hack html tags in there...there's probably a better way to handle it. The email wouldn't take terminal color codes etc since it's not a terminal interpretting them so I had to go with html.
You can follow this link to set up gentoo to send from your own gmail address:
http://en.gentoo-wiki.com/wiki/Gmail_and_sSMTP
The result of all this would look something like this:
DEVICE : <HOSTNAME>
COMMAND : <COMMANDS_RUN> (or the command that it failed at)
RESULT : PASS or FAIL
CODE : 141
OUTPUT:
<the console output is shown here only if the thing failed>
Maybe this'll be useful to someone else in the future. The code could be cleaned up indeed etc but hey, it works. I'm working on an embedded device (Beagleboard-XM) so I have to leave it plugged in on top of the router and I can't monitor it 24/7 over serial console right.
UPDATE: I was stupid and forgot that my $RESULT variable is actually the same as $EXIT_STATUS after I changed the script up at one point; meaning...$RESULT is pretty useless..meh |

You could hook up your script to be executed at the end of the emerge process (via a config variable POST_CMD). Since your script will be run from inside my script, it will actually be able to access the internal variables of my script, in particular the array exit_status which contains the number of failed and skipped packages. _________________ emerge --quiet redefined | E17 vids: I, II | Now using kde5 | e is unstable :-/ |

No real need, in my opinion. A trivial wrapper script or bash alias will integrate this little script into your normal Portage workflow.
