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.

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.

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.


Cheers,
Jochen
