Alerts can be created based on tags or by setting criteria via the intuitive and powerful [search](https://logentries.com/doc/search/) capabilities of LogEntries. To not flood notifications it's possible to specify limitations for alerts, such as how many times an hour an event has to happen for it to trigger a notification. Notifications can be sent by email, mobile messaging or via [webhooks](https://logentries.com/doc/webhookalert/) (webhooks are sent server in real-time, so there's no need for polling for changes).

Pro Event and search updates can be viewed in real-time
In Live Tail mode events and searches update in real-time. Live Tail mode can be used in Aggregate View, that allows selecting a combination of logfiles to be viewed together, and with any log groups created. These events are supplemented with tags to allows getting an overview of current events quickly at a glance.
Pro Supports the most popular programming frameworks
Supports the most popular programming frameworks, including Ruby and node.js.

Colored indicators can be set that highlight events in a log in real-time based on given criteria. Criteria are set via intuitive and powerful search capabilities of LogEntries.
Pro Easy to set up
Logentries can be set up quickly and with relative ease.

Pro AJAX errors
Helps you know when the API call is failing so that you can quicky get to it.
Pro Event telemetry to reproduce error
Records action that led to the error which makes it easy to reproduce the error faster. Events recorded are console logs, network calls, route changes and user events, like clicks and inputs.
Pro Network performance monitoring
AJAX monitoring shows which calls are running slow and how many calls the app is making to the backend. Also, provides data transfer reports and throughput reports.
Allows integrating various notification channels like Slack, Hipchat & Email. Notifies whenever there's a new error or a resolved error appears again.

Monitors page load performance along with the breakdown like Query stalling, SSL, TCP Handshake etc. It also provides in-depth monitoring, including duration filtering, URL filtering and AJAX calls made from the page.
Pro Drag & drop source map support
It's really easy to debug minify code. Source map support, not just beautifies the code, but also fetches code context.
Pro Daily error reports
Daily reports help understand anomalies that triggers errors. Also, gives top erroneous browsers, URLs etc within the report.
Pro There's a free plan
ErrLytics provides a free plan which helps to monitor small-scale websites, a feature that is mostly absent in other services.
Con Confusing interface
The interface is packed with features and options, many of them I'm not sure what they do at all.
Con Limited search capabilites
Compared to Elasticsearch and other competitors, search syntax has few features, apart from regexp and NOT/AND/OR combining. E.g. has no syntax to determine if a field is absent.
Con Character limit for each log entry
Currently log entries are limited to 8192 characters, if your log entry runs over this amount then it will be truncated where the excess log will be a new entry in the UI. This can easily cause a problem JSON structure with java stacktraces.
The average plan is over $1.5 per GB, which can get very expensive for any sort of reasonable volume.
Con Short retention
The retention is very short (14 - 30 days).
Con There's a limit of 100 logs per server
Should you have a webserver that hosts many sites, you'll hit this undocumented limit. The token-based alternative solution is inconvenient to set up and maintain.
Con Can't track the source of errors in 3rd party libraries
Con Insufficiently secure web client logger
No progress since this was reported in September 2013.
Con Grouping is unsorted and limited
Eg. you can't really check what browsers people use, because the report is limited to 40 unique strings.
Con Blocked by ad blockers by default
https://easylist-downloads.adblockplus.org/easyprivacy.txt includes logentries
Con Signing up requires phone number
Con No CDN for the web client logger
Con TypeErrors (X is not a function) are not tracked
Loggly catches them by default. LogEntries doesn't seem to catch them even if
catchall is set to
true. See the GitHub issue.
