Hi Eric, - Is it able to collect logs from linux, windows, solaris, VMware, Citrix, > IIS, Apache, Tomcat, Databases and materials? >
Graylog comes with a variety of inputs out-of-the-box (like Syslog, GELF, Kafka, AMQP, or plaintext) and is extensible via plugins (see https://marketplace.graylog.org/addons?kind=plugin) and there are other agents that can be used in combination with Graylog to collect data from sources not directly supported (like Graylog Collector, nxlog, *beats, or logstash). Also see http://docs.graylog.org/en/1.3/pages/sending_data.html and http://docs.graylog.org/en/1.3/pages/collector.html. > - What is the log capacity? How much events is it able to handle and how > many can it store? (Or does it have to be linked to my own database?) > Graylog can scale horizontally, so the processing performance depends on how much hardware you'll throw at Graylog and the backing Elasticsearch cluster. There are Graylog setups processing over 100k events per second and collecting multiple terabytes of data per day. See http://docs.graylog.org/en/1.3/pages/architecture.html and http://docs.graylog.org/en/1.3/pages/load_balancers.html. > - Do I need to install something on every equipment I want to manage or a > single instalation on my server will do the job alone? > This totally depends on the type of equipment you have and which kinds of remote logging capabilities it has. Most network appliances support some sort of syslog which can be consumed by Graylog. > - Is it able to filter the logs coming to the server? > Yes, see http://docs.graylog.org/en/1.3/pages/extractors.html and http://docs.graylog.org/en/1.3/pages/blacklisting.html. - Can I create accounts to log in graylog to secure it? > Yes, Graylog supports multiple users and also integrates with LDAP and Active Directory, see http://docs.graylog.org/en/1.3/pages/users_and_roles.html. - Can I configure some alarms like a mail when some events happen? > Yes, see http://docs.graylog.org/en/1.3/pages/getting_started/stream_alerts.html. > - how much does it cost? > Graylog itself is free (as in speech and as in beer), but you can support the development (and put some ease to your mind) by buying a support contract, see https://www.graylog.org/professional-support.
