Why it executes the script every 2 minutes?
Shouldn't it execute every 10 minutes ?
*\10 * * * * /usr/bin/python /var/www/py/LSFchecker.py
*\10 * * * *
Should probably be
*/10 * * * *
You can try:
00,10,20,30,40,50 * * * * /usr/bin/python /var/www/py/LSFchecker.py

psql: error: could not connect to server: Connection timed out
Is the server running on host "name-prod.postgres.database.azure.com" (10.110.0.4) and accepting
TCP/IP connections on port 5432?
If I run traceroute inside the POD

It used to work for 8 days and then suddenly stopped.
Postgres is placed in subnet 10.110.0.0/16
Aks in prod-private-eks 10.240.0.0/16 with Microsoft.Sql service endpoint added
What could be the issue?
Would suggest you to Open a Firewall Port for PostgreSQL if haven’t
Please refer this document to how to Open a Port in Windows Defender Firewall:
https://manifold.net/doc/mfd9/open_a_firewall_port_for_postgresql.htm
In PostgreSQL’s case it’s typical to use port 5432 if it is available. If it isn’t, most installers will choose the next free port, usually 5433.
Reference: postgresql port confusion 5433 or 5432?
I need to add a new task for crontab which will execute it in a different TZ than the local machine time.
I succeed to do it as you can see in the example below, but the problem is that from time i changed the TZ all the jobs after refers to the new TZ
* * * * * rubHello.sh
0 19 * * * runKuku.sh
CRON_TZ="Europe/Rome"
17 13 * * * /tmp/job1.sh
0 18 * * * /tmp/Job2.sh
in the example above, job1 runs in Europe/Rome as my request, but also job2
runs in that time which is NOT OK.
it there a way to tell crontab change the TZ for only specific task and get back to default crontab TZ for the next jobs after?
Thank you.
Try this (presuming you're in Istanbul), CRON_TZ variable should be set before your cron entry :
* * * * * rubHello.sh
0 19 * * * runKuku.sh
CRON_TZ="Europe/Rome"
17 13 * * * /tmp/job1.sh
CRON_TZ="Europe/Istanbul"
0 18 * * * /tmp/Job2.sh
OR
* * * * * rubHello.sh
0 19 * * * runKuku.sh
0 18 * * * /tmp/Job2.sh
CRON_TZ="Europe/Rome"
17 13 * * * /tmp/job1.sh
This should work, I believe:
* * * * * rubHello.sh
0 19 * * * runKuku.sh
17 13 * * * TZ="Europe/Rome" /tmp/job1.sh
0 18 * * * /tmp/Job2.sh
I am using node-cron. Please help to explain to me the different between:
var pattern_1 = '58 * * * * *';
var pattern_2 = '*/58 * * * * *';
when running this function:
new CronJob(pattern, function() {
console.log('lalalalala')
}, null, true, 'America/Los_Angeles');
As described in cron man page:
Step values can be used in conjunction with ranges. Following a range
with ''/'' specifies skips of the number's value through the
range.
and:
Steps are also permitted after an asterisk, so if you want
to say ''every two hours'', just use ``*/2''.
So:
var pattern_1 = '58 * * * * *';
executes "at 58th seconds of every minute". The second pattern:
var pattern_2 = '*/58 * * * * *';
executes "every 58 seconds".
The first patterns will run your cronjob every 58th second: 00:00:58, 00:01:58, 00:02:58...and so on.
The slash character can be used to identify periodic values. For example */15 * * * * * means, that your job will run ever 15th second: 00:00:15, 00:00:30, 00:00:45 ...and so on.
In my opinion */58 doesn't look very useful. This will execute every 58th second of every minute, so just use the first one.
The second pattern:
var pattern_1 = '58 * * * * *';
It executes at "58th seconds of every minute".
The second pattern:
var pattern_2 = '*/58 * * * * *';
Same as pattern 1 so it also executes at "58th seconds of every minute".
I want to run cron job daily at midnight. For this I am using
0 0 0 1-31 * *
but it doesn't work for me.
I am using the node cron. Please suggest the valid format.
You don't need to set all the fields. Set just first three and it'll take care of running every day at midnight
0 0 0 * * *
It's quite simple....
The below is the code to run crone job every day 12 AM..
var job = new CronJob('0 0 0 * * *', function() {
//will run every day at 12:00 AM
})
For more https://www.npmjs.com/package/cron
You can try this format too.
var CronJob=require('cron').CronJob;
var cronJob1 = new CronJob({
cronTime: '00 00 00 * * * ',
onTick: function () {
//Your code that is to be executed on every midnight
},
start: true,
runOnInit: false
});
To understanding something more about cronTime, See the following codes:
cronTime: '00 */3 * * * * ' => Executes in every 3 seconds.
cronTime: '* */1 * * * * ' => MEANING LESS. Executes every one second.
cronTime: '00 */1 * * * * ' => Executes every 1 minute.
cronTime: '00 30 11 * * 0-5 ' => Runs every weekday (Monday to Friday) # 11.30 AM
cronTime: '00 56 17 * * * ' => Will execute on every 5:56 PM
Here is:
var CronJob = require('cron').CronJob;
var job = new CronJob('00 00 00 * * *', function() {
/*
* Runs every day
* at 00:00:00 AM.
*/
// DO SOMETHING
}, function () {
/* This function is executed when the job stops */
},
true /* Start the job right now */
);
0 0 * * *
This pattern will run CronJob job daily at 00:00

I posted a question the other day about setting alternative minutes in cron, and i was given a lovely simple answer.
0-59/2 * * * * first_script
1-59/2 * * * * second_script
This worked brilliantly, however i have seen realized that i need my scripts to run quicker than every minute.
I know cron doesn't support seconds, but you can bluff it by using sleep, like so
* * * * * /foo/bar/your_script
* * * * * sleep 15; /foo/bar/your_script
* * * * * sleep 30; /foo/bar/your_script
* * * * * sleep 45; /foo/bar/your_script
So i need to combine the both of these so that i can get them to run alternatively every 15 seconds for instance.
Any ideas?
Ended up with the following code to get my scripts to run in shorter intervals than 1 minute.
* * * * * /usr/bin/php -q /path/to/file/script1.php
* * * * * sleep 15; /usr/bin/php -q /path/to/file/script2.php
* * * * * sleep 30; /usr/bin/php -q /path/to/file/script1.php
* * * * * sleep 45; /usr/bin/php -q /path/to/file/script2.php
