I'm going to tack on to what Nadim said. I may be a "pure Elastic" fan but for most small shops, I think Graylog is the way to go. It gives you as much storage as you can put behind it (it's elasticsearch for storage under the hood for indexing), you can feed it with logstash so you can do all your parsing (schema on write) and enrichment up-front, it supports parsing at search (schema on read) and it has an excellent support community (in addition to paid support, if you go that route). That doesn't mean I'm not going to say, "you should also look at the Elastic Stack" =) The biggie for me is the enrichment up-front. We get an MFA log, we pull the user name and IP, then we add data from Active Directory, we add data from inventory, we add GeoIP data (really just after ASN / company info), then we store the log event with that data added. It makes, e.g., doing a search like "give me all the MFA events for this department that weren't from a local internet provider" really quick and easy - it isn't having to crawl through and find all the usernames for that department AND do GeoIP at search time, it's just filtering on data that's already there. "show me when someone from x departments has a login event from a *new* Internet provider" -- super simple, it's just looking for a new value to appear in the geoip ASN field. You do need to know your log data for it to be effective... kmw On Thu, May 13, 2021 at 7:44 PM Nadim El-Khoury < 0000024d485fe2c4-dmarc-request () listserv educause edu> wrote:
Hi Jonathan, We use Graylog here at Springfield College. We are using the open-source version, and we are so far happy with it. We started using it a couple of months ago, and so far, we indexed around 103+ GB of data from our Palo Alto firewalls alone. We did not even count the data from the ASA VPN devices and other systems. As a small college with limited funds and resources, we would not be able to afford the other products.

That you would recommend? (I’ll take warnings too!) We’re looking to make a change within the next 12-18 months and I could use honest feedback on solutions, experience, cost, dedicated headcount support.
