Bash script to check health checks of multiple servers

I had to check over 20 servers to verify they were updated with a new build. The servers had a health check page that had this information along with whether the server was up-and-running. I wrote this quick-and-dirty bash script to do just that. 

for i in jetson1 jetson4; do for j in {1..10}; do curl -igX GET "http://app$j.tpa.$i.coresys.tmcs:8080/health/heartbeat"; done; done | grep -E '1.4.37' | grep -E "Overall Status: Success" | wc -l<br>

Hope this helps someone. Cheers!

My custom bash prompt

I wanted more information in my bash prompt, such as date/time and the directory I was in.  Here’s what it looks like:

bash_prompt

And this is what I added in my ~/.bash_profile:


PS1='${debian_chroot:+($debian_chroot)}\d \T &gt; \[$(tput sgr0)\]\[\033[01;32m\]\u@\h\[\033[00m\] : \[\033[01;34m\]\w\[\033[00m\]\n\$ '

Run source ~/.bash_profile and enjoy. 🙂

BTW, there’s also a website that you can use to create your own: http://bashrcgenerator.com/.

Mongo DB: Iterate through a MongoCollection

This is specifically for Mongo 3.x, where MongoCollection is preferred over DBCollection. Adding for personal archiving.


MongoCollection<Document> mongoCollection =
            getMongoCollection(databaseName, collectionName);

        FindIterable<Document> documents =
            mongoCollection.find(eq(COLUMN, "lastName"))
                .sort(ascending("lastname"));

        for (Document document : documents) {
            ...
        }
