We are using the `ELK stack (logstash, elasticsearch, kibana)` to analyze our logs. So far, so good. But now we want notification generation on some particular kind of logs. Eg When a login failed logs comes more than 5 times (threshold crossed) an email to be sent to the sysadmin. I looked up online and heard about `statsd`, `riemann`, `nagios`, `metric` filter (logstash) to achieve our requirement. Can anyone suggest which fits best with ELK stack?? I am new to this.

The solutions I've seen for things like this in ELK usually are on the lines of using logstash to reparse the logs in ES and use some output (e-mail, nagios, Zabbix) to do the alerting. For now I've stick with using OSSEC ([www.ossec.net](http://www.ossec.net)) to do my alerting and "just" use ELK for log analysis.

@Antonio: I use email output for a particular pattern in a log. But for example, when a particular logs comes more than 5 times, for alerting for this a state needs to be maintained which is not there in logstash. I don't know about OSSEC. But how to use it to achieve the above? Presently logstash reads logs, ES stores it and kibana presents it. How OSSEC fits here?

I haven't done it yet.. but my plan is to simply do REST searches.. and if I get a lot of alerts and want to check often.. I'd switch to setting up percolators. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

OSSEC is a HIDS (Host Intrusion Detection SYstem), its objective is to parse logs, check the logs against rules and send alerts. It has a vast amount of rules already defined, so when it starts checking your logs it will start firing alerts. In my architecture OSSEC fits outside the ELK stack. It parses the logs (as Logstash) but write alerts to files and send alerts by email. I've another logstash instance that reads the alerts from OSSEC, so I can have a nice Dashboard for them on Kibana.

So inputing log files to logstash-parse-store-view them and separately doing this for alerts:ossec-parse-alert, will this not create redudancy?? Does OSSEC has rules for threshold crossing??

Yes, it adds redundancy, but, for now, I think its the best option. OSSEC has a very flexible analysing system, and it should fit your needs without much trouble.

We use Nagios for alerting. I originally was using the nsca output plugin for logstash, but found that it took close to a second to execute the command line nsca client, and if we got flooded with alert messages, logstash would fall behind. I've since switched to use the http output and send json to the nagios-api server ([GitHub - zorkian/nagios-api: A REST-like, JSON interface to Nagios](https://github.com/zorkian/nagios-api)). That seems to scale a lot better. We do also have metrics sent from logstash to statsd/graphite, but mostly so I can see message rates. mike On Monday, June 23, 2014 4:50:22 AM UTC-4, Siddharth Trikha wrote: > We are using the `ELK stack (logstash, elasticsearch, kibana)` to analyze > our logs.

We have and use SPM [http://sematext.com/spm/](http://sematext.com/spm/) for all our metrics (ES, Kafka, Apache, MySQL, Hadoop, everything) and we feed our logs to Logsene [http://sematext.com/logsene/](http://sematext.com/logsene/) (it has a Kibana UI and a "native" UI). SPM has alerting and anomaly detection, so we use that to get out of bed early (nah, not really), but we currently lack alerting in Logsene (i.e. alerting on numerical data in logs or on patterns). Since Logsene has Kibana UI and can be fed via Logstash and has an Elasticsearch API and backend, that's the closest we've gotten to ELK+Alerts. ## Otis Performance Monitoring \* Log Analytics \* Search Analytics Solr & Elasticsearch Support \* [http://sematext.com/](http://sematext.com/) On Wednesday, June 25, 2014 11:18:01 AM UTC-4, Michael Hart wrote: > We use Nagios for alerting.

Nagios recently released a new Log Analysis [http://www.nagios.com/products/nagios-log-server](http://www.nagios.com/products/nagios-log-server) product called Nagios Log Server which is built using the ELK stack and provides alerting, authentication, GUI logstash configuration for the whole cluster and a ton more. Alerts based on any query can be sent directly to Nagios, Email, SNMP traps, custom script execution and more...
