You don't monitor web logs, you ship the logs to cold storage every [crontab spec units for time :)] and monitor your hosts and network for unusual activity.
If anything happens, THEN you look at the logs. The signal/noise ratio of the average web host logs makes combing through them just not worth it.
There are tons of products out there - have a look at OSSEC (https://www.ossec.net/), it's open source and free.
That looks like somebody messed up while converting image data to vector data in their GIS.
Sometimes you see stuff similar to this when you have a bunch of coordinates and a few of them are corrupted - then the lines would shoot off somewhere, and sometimes you might not even notice it. BUT this doesn't look like that - hell it could be pastefuck.
Why isn't there a big fat blinking TRY ME button somewhere on that site? And if it's there, why isn't it in my face? And don't ask me to create an account before showing me the goods, because I won't.
Aw man, I've turned into the typical negative HN commenter. My mother would be so ashamed.
Well, these hits on your ssh port target only the most low-hanging of the low-hanging fruit - i.e. common username/password combinations. Nobody's brute-forcing you anything, they're just trying some common user/pass pairs at random. Disable remote login by password in lieu of key authentication and you can sleep tightly while listening to the soothing hum of failed login attempts crashing upon your airtight SSH configuration.
In the long run, I've found that years pass and connections configs get lost and you forget which fancy port you used for your SSH connection on that server. Maybe YOU have an ironclad convention, but your co-worker had another one, and you can't remember what port he used. And he's left the company or died or joined a cult.
Kids, leave your SSH ports alone. A config is just a config. But keys are forever.
