loGrobot / logXray

What is LoGrobot? LoGrobot (also known as logXray) is an advanced centralized 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 forcing them to read a ton of documentation, learn new programming languages or be a master of complex regexes. It is a plug n play utility built to simplify the day to day log monitoring tasks of dev ops engineers, application developers, monitoring specialists, system and database administrators. Additionally, LoGrobot is equipped with a massive arsenal of versatile features which enables it to monitor, analyze and alert on any log file however is necessary. In other words, with LoGrobot, you get to avoid having to write or tweak any log monitoring script ever again!

Common Log File Monitoring Scenarios

Do you have application logs, database logs or system log files that need monitoring? As long as each one those log files reside on UNIX systems or an NFS drive (for windows logs), they can be monitored!

Apache / HTTP log monitoring

Alert, Report, Graph Apache Access logs - Pull out as much information as you wish from access / http log files. Alert on the number of entries containing specific status codes. Graph all status codes...automatically.

Watch logs for Expected events

Monitor log files for expected record of events - send alert notifications if those events are not found in the latest scan of all new entries added to the log!

Pattern Exclusion in Log Checks

Exclusions - Specifying a list of patterns to exclude when attempting to isolate unique entries of interest from monitored log files. When a log check reports an issue, use this option to get rid of unwanted entries from the list of error patterns detected.

Show offending entries in alerts

Detailed Log Check Notifications - Whenever a log check detects entries from a monitored log containing the patterns you tell it to watch for, it will show all those lines in the alert notification it sends out to you. If you wish to only see the actual lines from the log that triggered the alert, add 'noextraoutput' to the logXray command.

Show less information in alerts

Whenever a log check detects an issue in a monitored log, do NOT show the offending entries in alerts.

Monitoring dynamic log files

Monitor and alert on dynamic Logs - Take into account log rotation and monitor accordingly. Dynamic logs are log files that change names frequently..i.e. every minute, hour or daily.

Time frame tailing of log files

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.

Monitor multiple patterns in log

Use one check to monitor multiple patterns within a log file - set thresholds per pattern. Get alert notifications on a particular pattern if and only if the number of entries found containing that pattern is greater than the thresholds you specified.

Monitor a directory of log files

Monitor a directory of log files - avoid specifying each log file separately. Monitor a specific log file across several different directories.

Monitoring Log File Time Stamp

Check time stamps of specific log files - Set up monitoring checks to alert when those logs stop updating.

Monitor Directory File Count

Directory File Count Monitoring - Monitor the number of files in a directory. Alert if the number of a user specified type of file in a specific directory breaches set thresholds.

Graphing all log file metrics

Automatically generate live graphs for all log file monitors / log file checks - Be able to see historical data on application, database and system health / behavior.

Monitor Log File Size

Check log file size - Monitor the disk space consumption of specific log files - Alert if the size of a monitored log grows past user specified thresholds.

Custom Monitoring Agent

If you do not have Nagios, Zabbix, Zenoss or any similar monitoring application installed in your environment, that's ok. You will still be able to monitor remote log files with our custom monitoring agent, which is included in the logXray package.

Using logXray w/ NRPE (Nagios)

NRPE - Monitor logs using the very common nagios NRPE monitoring agent. Follow these instructions to set up logXray on the remote hosts on which you have logs to monitor.

Custom log files

If you have log files that need to be monitored in a very specific way, email us to request custom development - All customers get 2 FREE requests for customization with purchase of LoGrobot.



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.

Preview

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.

Preview

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.

Preview


Graphing Historical Data

Be able to isolate unusual trends a lot faster either through glancing at the graphs or receiving notification alerts on anomalies detected.

Preview

Trend Application Behavior

Visualize the health of your applications, databases, system logs with up to the minute details on log behavior.

Preview

How busy is my Application?

Avoid manually sifting through log files - Get the answers you need with a simple glance at live graphs of all your monitored UNIX logs!

Preview


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.

Preview

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 actual entries from the log containing the offending pattern!

Preview

Multiple Pattern Log Monitor

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

Preview












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 anomalies (unusual rises and/or drops) in any measured log metric!






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 - if a system is being taxed, checks will not run on time, and if they do, they'll take a bit longer - an additional second or two - to complete).


If you do not wish to see extra information in your log file alerts and only care for the actual entries found in the log, that is also possible. See the image below. Just add the option 'noextraoutput' to your logrobot / logXray command.








Complex log monitoring made extremely simple

With just one log check, monitor multiple patterns within a log file - When an alert is generated, see the actual offending string(s)/pattern(s) that triggered it. Additionally, with the unique artificial intelligence built into logXray, users can now set conditional alerting on special log entries..i.e. when special entries are detected in a log, look in a certain column of those entries for a specific value. Alert as warning or critical if that value breaches set thresholds.
