loGrobot / logXray

What is LoGrobot? LoGrobot (also known as logXray) is an advanced Log File Monitoring tool developed for UNIX systems. It allows UNIX users to painlessly and reliably monitor log files on an unlimited number of hosts without having to read a ton of documentation or learn new programming languages. It is equipped with a massive arsenal of robust, versatile features capable of handling any log monitoring task given to it, no matter how complicated or customized it is..i.e. monitor multiple patterns in one log, with different alert thresholds for each pattern, monitor log size, log growth, log timestamp, alert on a directory of log files, automatically identify unusual activities or anomalies in monitored logs and much more!

Cool features


Monitor and alert on UNIX log files without having to learn any programming languages or be a master of complex regexes. Download logXray today and begin monitoring your logs within seconds!


Automatically convert all measurable log file metrics into simple and easy to read diagrams. Chart your own log file metrics or have logXray automatically send them to us. We'll graph them for you!


Utilize graphs, notification alerts and other variables to identify abnormal events in your important log files. Scan application, database & system logs with automated intelligence, identify unusual drops or surges in activities.


Generate quick reports on past notification alerts on all monitored log files - Create color-coded excel spreadsheets directly from the command line or from our php web interface, avoid having to dig through archives!

What is the Ideal Log File Monitor?

LoGrobot is the ideal log file monitor. Why? Because unlike other tools, it isn't unnecessarily complicated. It is an affordable plug n play software that can be used by anyone on any UNIX system. It was built over the span of 5 years to specifically reduce the level of effort required to monitor log files efficiently and reliably.

Unlike other tools, there are no convoluted documentations for you to read. There are no scary installations or heavily involved configurations for you to stress over. Basically, all the hard and tedious work you would have had to do have already been programmed into the tool. You simply reap the benefit of having an intuitive software that will automatically perform all your log monitoring tasks for you, with ease.

Some of the many labor saving capabilities of LoGrobot include:

  • Monitoring different patterns in different log files...with one check...and no configs!
  • Configurable to alert on single strings, patterns, keywords in one or more log files
  • Monitoring of different patterns in the same log file (without any configuration)
  • Allows assigning different thresholds to each pattern in a multi-pattern log check
  • Monitors log file timestamps, log file growth, log file size and directory file count
  • CLI Usage: Allows for the viewing of log entries in timeframes (no more random tails)
  • Monitor a directory of log files / detect exception patterns in all monitored logs
  • Recognize system or network abuse (through mathematical analysis of log file data)
  • Detect intruders or attempted intrusions (through the use of user-specified patterns)
  • Scanning, monitoring and alerting on log files of any format, type or size
  • Graphs remote log metrics; users avoid having to maintain their own graphing server

Are my logs supported?

Yes. All conceivable log files are supported. LoGrobot is versatile.


Tail log files intelligently via time frames if the logs are date and time formatted. For example, be able to pull out log entries from 5 minutes, 10 minutes, 1 hour ago till now. Avoid grabbing random number of lines.

Log File Monitoring - Alerts & Graphs

Automatically graph several log file metrics...without any extra configuration on your part!

New Log Entries

2-day Range - Aggregate of 4 different log files on 4 different hosts. This graph shows the frequency with which each log is being written to.


Log Size Monitor

2-day Range - Log Size - Trends the size of log files. Allows users to keep an eye on log rotation to ensure logs are being rolled over at the expected size and time.


Application Log Errors

2-day Range - Application Log Monitoring - Monitors applications with multiple log files - Graphs the number of user-specified errors detected in monitored logs.


Log File Growth Monitor

Monitors the size of a specific log file. Alerts if log file size remains the same as it was during the last scan. This log check can also be configured to alert if growth is beneath user-specified thresholds.


Single Pattern Log Monitor

Monitors a log file for a specific string. When that string is found in the log file, this alert shows the complete lines from the log containing the offending pattern!


Multiple Pattern Log Monitor

Uses one check to monitor several strings within a specific log file - Helps users avoid creating separate log file checks for each string...unless necessary!


Simplicity via Graphs

Aggregate graphs of multiple log files from several different hosts and/or servers into single graph(s) - See the logging activities of applications, dbs, servers all in one place. Beautify your log file activities - Visually inspect graphs / charts of all monitored logs - Easily identify Rises & Drops in the frequency of entries!

Detailed Alert Notifications

See detailed information on the log file being monitored i.e. log size, total number of entries in log, latest count of new error patterns, rate at which log file is being updated, percentage of error patterns in relation to total new entries, the scheduling consistency at which log check is running (helps identify when system is under heavy load!)

Multiple Patterns in one Log

With just one log check, monitor multiple patterns, strings or keywords - When an alert is generated, see the offending string(s)/pattern(s) that triggered it!

Simple. Intuitive. Powerful.

Get notifications when:

  • specific strings, patterns or keywords are dumped into your log files
  • expected patterns of strings ARE NOT found within specific log files
  • unfamiliar lines are introduced into your system and/or application logs
  • critical log files stop receiving updates after a user-specified period of time
  • a log file is moved, deleted or no longer exist where it should
  • a log file lacks the proper / expected permissions...i.e. read access
  • monitored log files begin to consume too much disk space (unusual growth spurts)
  • the size of a specific type of file in a specific directory breaches set thresholds
  • size/growth of a log goes above user-specified thresholds (warning/critical)
  • the number of specific files in a specific directory exceeds user specified thresholds
