Hey HNers,

We're excited to announce a major update to SeaLion. SeaLion is built on top of a lot of feedback from SysAdmins, DevOps and many industry experts who helped us mold this product to what it is today.

If you're new to SeaLion, it's a Linux server monitoring tool designed to view the raw output for critical events and optimize server performance.

With the latest update, we have added integrations with popular services like MongoDB, Redis, NGINX, Apache, and MySQL. One agent to monitor all these services and you can use the custom framework to monitor any other Linux-based service.

To help you get started, we are allowing you to monitor your first server for FREE! Go ahead, give it a spin. We would love to know your feedback.

Here is a quick video overview of the product - https://www.youtube.com/watch?v=_9ES7nmZ948

Don't hesitate to ask a question, you can also take a look at our knowledgebase for documentation and FAQs - http://kb.sealion.com/

Once you have custom commands set up, you can rely on alerts to zero-down on the issue and debug it with ease.

You can make use of historical data to go back in time, analyse and debug issues.

Run the curl command once you sign up. Or, download the tarball and install it manually.

Good catch. Fixed it. Thanks!

Ah! Here's the list - https://sealion.com/features

A huge thank you for all your comments and feedback. I've updated the blog post with 6 more wishlist items based on your replies.

You might want to check your Play Store link and update again. It's currently broken.

Agree! Market research is the key. We wanted to share our findings. Hope this comes handy to others planning a HN launch.

An HN post title is of 80 characters. That’s the space you have to lure the reader. We spent more time coming up with the title, than to write the product launch blog. We sat down and listed all the posts that did well in the past few months. Later, we narrowed down on the ones that made sense to us and grouped them by the tone. Here are those:

a. Straightforward titles about the product Show HN: Meteor, a realtime JavaScript framework Show HN: Automatic weekly meal planner, also plans your leftovers Show HN: Ditch Black Text to Read Faster, Easier Show HN: Codecademy.com, the easiest way to learn to code Show HN: a web-based xkcd-style comix editor Show HN: Remove backgrounds from images online Show HN: Imagine a search engine that removed top million sites from its index Show HN: movies.io — torrent search like it should be Show HN: Hackershelf. Community curated collection of legally free books Show HN: Webflow - Design responsive websites visually Show HN: fontBomb - Stylishly destroy the web Show HN: Non-Confusing, Visually Correct Slider Toggle UI

b. Problem/Solution title Show HN: We got tired of asking ‘What browser are you using?’ and created this

c. Title by an individual Show HN: 6 months ago I quit my job to pursue indie dev. Here is our first game Show HN: Weekend project, Intro.js Show HN: I Created the Inverse of Angry Birds Show HN: My seven minute workout timer evening project Show HN: I hacked my microwave with a Raspberry Pi

d. Title by a group Show HN: We open sourced Lockitron’s crowdfunding app Show HN: We just built a site that saves lives We then came up with the titles that we could use for our product Show HN: Hosted Linux sar - SeaLion Show HN: We got tired of asking ‘Why Linux server went belly up’ & created this Show HN: We’re tired of asking ‘What’s wrong with our Linux servers’ & created this Show HN: Tired of asking “What’s wrong with our Linux servers?”, we built this Show HN: The Linux sys-admin story. Why did we create SeaLion? Show HN: Why did we create SeaLion? The Linux sys-admin story Show HN: A tool from sys-admins to sys-admins. The SeaLion story. Show HN: We wanted to simplify the tasks of a sys admin and created this Show HN: Dear god, save sys-admins. The SeaLion story. Show HN: A tool from sysadmins to sysadmins. Hosted Linux SAR. Show HN: Hosted Linux SAR. A tool from sysadmins to sysadmins.

Our product is a sysadmin tool. So we ran these titles by resident sysadmins on what would push their buttons and chose this:

Show HN: Tired of asking “What’s wrong with our Linux servers?”, we built this

This title did make the sysadmins tick. We got nearly 10K visits in a few hours and brought down our servers.

This is one of the many things we did. We have spoken about the whole exercise in the post.

This discussion has happened before.

For those who are interested, here's the story behind it - http://blog.cloudmagic.com/2013/10/30/the-cloudmagic-story/

Love to get your feedback.

How is this any different when compared to rafflecopter.com?

My company uses LastPass. It's a nice service. - The admin will have control over what service you need to have access to. - Change password often and will be accessible by team mates without having to remember anything.

Simplifies a lot of other things, all you have to remember is the master password.

Point noted! Thanks.

Sorry about that. Could you please let us know what browser you're currently using?

We wanted to make your job easy and hence provided a one-line installation command. You can always know what's happening.

1. Agent installation script is available at https://agent.sealion.com. Feel free to check it out.

2. We create a non-privileged user using the above script. Hence, we cannot run privileged commands without your permission.

3. The data logged is solely for your usage. The data is stored in secure Amazon servers. Will improve the privacy policy.

4. BTW, we are thinking of providing installer packages and also release the agent code under an open source license to alleviate your concerns.

Apart from HN, we were doing great on reddit.com/r/sysadmin/. Crazy traffic. Unfortunately, the site couldn't handle it. Ngnix was going out of TCP handles. Arrrrrrgh, we should have done a better job in load testing. Fixed it by increasing filehandles. Give it a spin now!

There's no distinction as such. You pay a flat $19 per server.

We are glad you liked our tool :-) Point taken on pricing.

How can we be sure that the package that's being installed is the one that you intended to be installed? We will give "checksums" with our agents in our upcoming releases.

How can I be sure that the install will be identical across all of my servers? Whenever you install SeaLion Agent, the most latest binary is installed. The agents in other servers are also updated, hence making them identical always.

How can I pin a version that I've vetted for security holes? SeaLion agents are released after rigorous testing, to ensure we do not leave any security holes and features, currently SeaLion Agent is designed for auto update.

How can I distribute this to servers that don't have arbitrary internet access? SeaLion agent requires Internet access to send data to its server. Hence internet access is mandatory.

How do I configure selinux/apparmor to work with your tool? SeaLion agent works fine with SELinux in enforcing mode without any specific configuration.

How can I uninstall this cleanly? sudo /usr/local/sealion-agent/uninstall.sh

Yes we wanted to give you the flexibility to see what we are installing on your servers. We understand the importance of checksums and will be realizing checksums for our agents in future releases.

Currently, SeaLion agent is meant for 64-bit machines only. 32-bit agents coming soon.

Got your point. Will fix the design. Deceiving was never the intention. Just wanted to display the social proof of the parent company.

BTW, did you give it a spin?

Thanks for the feedback. This is just the start, we have a lot to add. More on our roadmap here: http://blog.sealion.com/post/62987598857/why-did-we-create-s...

And yes, our target audience is users having multiple servers. You can use nagios and some other tools for logging data from few servers. Handling and debugging of logs spread across several servers is a pain in the neck.

The command you will be executing is to download and install the SeaLion agent.

SeaLion requires you to use sudo to install it as a service so that it will automatically restart whenever system reboots. All the commands executed by the SeaLion agent are run in the context of Sealion user which is a normal system user.

Thanks for your great feedback. We wanted to build a framework which can be easily extendable by adding custom commands. This is just the beginning, we will soon roll out more tools which will help integrate tightly with your server and applications.

We plan to integrate monitoring and many other related features after analyzing how the users are using our system. Regarding monitoring network layer, you can always write your own bash which records network activity. Interesting thoughts, we have added them in our pipeline.

We are @SeaLionTeam on twitter, we would love further inputs from you
