Does combat log misses something ?

If you wanna take a look at the entire combat log you can find it here

• Shalas · 05/31/06, 5:16 AM

22:16:24.656 MT is at full health
22:16:30.984 MT has taken 13802 damage since 22:16:24.656, and only been healed for 3690.

Unless your MT has over 10112 hp, he should be dead. There was a significant amount of overhealing in the first 14 seconds, and only two heals (plus a health stone) in the last 6 seconds.

Bullbrain · 05/31/06, 5:58 AM

Assuming your MT has 10000 health and HoTs/DoTs were omitted from the combat log:

5/30 22:16:22.843 Huhuran Berserks.
5/30 22:16:23.031 Princess Huhuran hits Durnagoth for 859. (128 blocked)
MT: 9141 HP
5/30 22:16:23.031 Zori's Flash Heal heals Durnagoth for 1209.
MT: 10000 HP
5/30 22:16:24.437 Princess Huhuran hits Durnagoth for 3. (1139 absorbed)
MT: 9997 HP
5/30 22:16:24.656 Your Lesser Healing Wave critically heals Durnagoth for 1825.
MT: 10000 HP
5/30 22:16:24.718 Princess Huhuran's Poison Bolt hits Durnagoth for 1494 Nature damage. (498 resisted)
5/30 22:16:25.109 Princess Huhuran hits Durnagoth for 896. (128 blocked)
5/30 22:16:26.343 Princess Huhuran hits Durnagoth for 783. (128 blocked)
5/30 22:16:27.000 Princess Huhuran's Poison Bolt hits Durnagoth for 2391 Nature damage.
5/30 22:16:27.562 Princess Huhuran hits Durnagoth for 1217. (crushing)
MT: 3219 HP
5/30 22:16:27.781 Zori's Flash Heal heals Durnagoth for 1268.
5/30 22:16:28.234 Your Lesser Healing Wave heals Durnagoth for 1102.
MT: 5589 HP
5/30 22:16:28.281 Princess Huhuran hits Durnagoth for 1231. (crushing)
5/30 22:16:28.859 Princess Huhuran's Poison Bolt hits Durnagoth for 1704 Nature damage.
5/30 22:16:29.062 Princess Huhuran hits Durnagoth for 726. (128 blocked)
MT: 1928 HP
5/30 22:16:29.187 Durnagoth's Major Healthstone heals Durnagoth for 1320
MT: 3248 HP
5/30 22:16:30.359 Princess Huhuran hits Durnagoth for 853.
5/30 22:16:30.843 Princess Huhuran's Poison Bolt hits Durnagoth for 1743 Nature damage.
5/30 22:16:30.984 Princess Huhuran hits Durnagoth for 766.
MT: -114 HP

The reason is quite simple. Lack of heals. There was a 3 second period between 5/30 22:16:24.656 and 5/30 22:16:27.781 where your MT received no heals(not even NS heals). That's a fatally long null period against a berserked Huhuran.

I'm not sure but our MT uses last stand at 30% and shield wall at ~20%.

Does exist out there a combat log analyzer ?

Kalman · 05/31/06, 9:45 AM

You have my name!!!!

Texas cage deathmatch, one man's math vs. another's.

I DEMAND AN INTEGRAL FACEOFF.

Kytrarewn · 05/31/06, 2:48 PM

Annoys me that there's still no decent combat log parser for WoW that provides the kind of information I'm looking for and doesn't crash with a large log file.

What kind of info are you looking for?

What kind of info are you looking for?

Number of skill uses, specific skill info, how hard the skill hits per mob, crit-rate per mob, number of glancing blows, how much I'm healed for, who heals me, etc.

Kalman · 05/31/06, 2:57 PM

I've been looking for an excuse to learn Perl, which would be very well suited for this sort of thing, I believe.

I might get bored. No promises.

Be great if you did. It's *slightly* annoying that in-game parsing tools (Damagemeters, Recap) are more powerful than out-of-game log-parsers.

Another thing that I'd ask, that should be very possible: Make it possible to calculate DPS/HPS/DTPS and, if possible, Overhealing, (assuming timestamps) over a given period of time automatically with the tool, rather than adding everything up with a Calculator.

I also wish WoW included a command such that you could name combat logs different things per day (Log 53002), etc.

Guess that's too much to ask though.

I was looking around for a combat log analyzer earlier and found this: http://www.jorgev.com/archives/000138.html

Has a link to a webpage that will do the parsing using perl, also has a link to a zipped file with the script itself in the comments section. I don't know if it does everything you want... I threw one log at it and there were some definite issues to work through (wasn't properly handling shadow bolts in my log, just gave me a list of complete resists). That said, it might be a good starting place if you do get bored and want something to build from or something to look at at least.

Are there any tools or resources people would recommend that do this sort of thing? Was debating trying to work up a solution as well, but if there's already something that exists that'd be nice to use. I found one windows app off curse, but it got... unhappy... when I passed it a 5meg log. Plus it didn't look like it would give me the kind of information I was really looking for, anyway.

I guess ideally you'd want to store the information so that you can view it from different perspectives... total damage done, skills used, etc... but also on a per enemy basis. Would also be nice to break that down so that you can view it raid-wide, class-wide, or by individuals.

Just a warning from someone who's walked this path: ahead lie demons. Beware.

Python's regex library isn't as powerful as Perl's, but the code is a damn sight more readable.

Kalman · 05/31/06, 3:25 PM

I spent the last 3 days reworking an assembly inner loop for a realtime control system to save something like 3 clock cycles. Unreadable is my stock in trade.
