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).

Con Confusing interface
The interface is packed with features and options, many of them I'm not sure what they do at all.
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.
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.
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.
