Overview<\/h1>\n

This is a short guide containing the steps I took to install Sealion<\/a> on an older Centos 5 server. Sealion is a activity monitoring service website that reports the status of your linux every 5 minutes. An agent running on your server runs a set of common commands (i.e. ps, top, vmstat, …) and reports the results back to the sealion.com site web console where you can view the results. \u00a0The Sealion introduction video<\/a> says it all.<\/p>\n

Installation Problems<\/h1>\n

The normal agent installation is usually a one line command but it failed on my server with this python dependency error:<\/p>\n

Performing dependency check…
\nError: Python dependency check failed
\nFile “..\/bin\/check_dependency.py”, line 19
\nexcept Exception as e:
\n^
\nSyntaxError: invalid syntax<\/p><\/blockquote>\n

The Sealion site didn’t list the dependencies and there weren’t any support documents that I could find. I emailed Sealion\u00a0and they replied with a link to this article for installing Python 2.7 on RedHat or SUSE<\/a>.<\/p>\n

Installing Python 2.7 got me one step closer but failed during the make process for the\u00a0sqlite module with the following error:<\/p>\n

\n
In function \u2018_pysqlite_set_result\u2019:\r\nerror: \u2018sqlite3_int64\u2019 undeclared<\/pre>\n<\/blockquote>\n
After some searching this article came up listing the error as a\u00a0known bug in Python 2.7.3<\/a>. I repeated the Python installation with 2.7.8 and substituted the correct Pthyon version into the agent installation curl command and all worked.<\/p>\n
Complete Procedure<\/h1>\n
    \n
  1. wget https:\/\/www.python.org\/ftp\/python\/2.7.8\/Python-2.7.8.tgz<\/li>\n
  2. tar -xvf Python-2.7.8.tgz<\/li>\n
  3. cd Python-2.7.8<\/li>\n
  4. .\/configure<\/li>\n
  5. make<\/li>\n
  6. make install<\/li>\n
  7. curl -s https:\/\/agent.sealion.com | sudo bash \/dev\/stdin -o\u00a0YOURSEALIONKEY\u00a0<\/em><\/strong><\/strong>-p<\/em> \/usr\/local\/bin\/python2\n
    <\/strong><\/em><\/em><\/strong><\/strong>Tip: The -p parameter specifies which version of python to use. Substitute\u00a0\/usr\/local\/bin\/python2\u00a0<\/strong>with the location your make install command placed Python and\u00a0YOURSEALIONKEY<\/em><\/strong>\u00a0<\/em>with the user key obtained from the Sealion add server screen.<\/li>\n<\/ol>\n
    Note: As part of the troubleshooting process I updated\u00a0sqlite but I’m not certain this was required. If you have problems try:<\/p>\n
    yum install sqlite.i386\u00a0sqlite-devel.i386<\/p><\/blockquote>\n
    This installed and started the Sealion agent and after a few minutes server and server data appeared in my Sealion.com console.<\/p>\n
    Thoughts About Sealion<\/h1>\n
    This is my first attempt at evaluating the Sealion linux server monitoring service. Other servers more up-to-date distributes installed the agent without issue.<\/p>\n
    The Sealion site is beautiful, functional, but a little sparse on content. There are only sporadic references to it across the internet (as of the time of writing) when I went searching for installation assistance. The lack of community activity leaves me a little worried about the reputation of Sealion but I can’t deny that the service is useful and easy to use. Their support email address responded quickly when I finally submitted my issue.<\/p>\n
    The service meets a need and has value to me. I hope to see it’s reputation increases\u00a0and turn\u00a0into\u00a0a reasonably priced service.<\/p>\n
