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, 6:16 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, 6:58 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 ?

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, 3:57 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, 4:25 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.

at first i thought this was an attempt at a math joke.

also, it might not be too difficult to write one in labview, as it has good file I/O, string parsing utilitys, and graphing abilities.

but then again, ugh, labview...

◊ Kalman · 05/31/06, 4:55 PM

It was an attempt at a math joke... I'm just not very funny with my integrals.

Yes. Ugh. Labview.

I have the very basics of a parser for MATLAB, from back when I was looking at the dagger spec in offhand question, but we're talking *very* basic parsing.

Gronx · 05/31/06, 5:05 PM

Come now, LabVIEW's your good friend, LabVIEW have never caused anyone countless hours of frustration, LabVIEW is good for you!

At least, that's what i'm trying to tell myself when working with it, and for some reason it seems to be nice to me when i keep telling myself that it's a good program.

I'm allmost reaching the point where i can make some decent data aquisition stuff with it, without any major problems.

You can do anything with LabVIEW, the nice NI people who convinced me to use it told me so at least, they couldn't possibly be lying, could they?

Hmm, maybe if i get boored enough, i might try this. For that to happen my Inet connection would have to be down for 1+ day, and i might have to find a way to work out my frustrations after using LabVIEW for an excessive ammount of time.

◊ Kalman · 05/31/06, 5:19 PM

The only thing I ever want to do with Labview again, after fighting with out automated dacq system using it for the past year and a half, is throw our site license out the window.

◊ Kalman · 05/31/06, 6:02 PM

Hmm. Looking into this, the major flaw I see is that it's harder to parse the format than it needs to be. Ideally, it would just log as:

Time: Originator: Type: Target: Amount: optionals

So you'd get

timecode: You: Hit: Ragnaros: 348:

or

timecode: Ragnaros: Hits: You: 2500: crushing

That'd make parsing significantly easier. Anyone know if it's possible to modify the /combatlog output format?

Unfortunately, I don't think so. I run Nurfed Combat Log, which modifies the way things show on screen to "You. Backstab. Onyxia. 585" or something of that ilk.

And this is what comes out
"5/29 20:05:44.640 Your Backstab hits Onyxia for 585."

◊ Kalman · 05/31/06, 6:22 PM

Somewhere I recall someone whose combatlog was modified to show events, but I can't remember if that was their ingame or /combatlog.

◊ Drauk · 05/31/06, 6:33 PM

No way to modify format. However, its possible to modify/reformat ingame log and than store it (events to be precise) into variable in a prefered format, and than work from there.

However making a "pre-processor" writen on Perl, or another regexp language looks much easier to me.

• Wodin · 05/31/06, 6:43 PM

The worst part are the special cases. For example, a hit and a block are recorded identically, except for the "(n blocked)" message at the end of the sentence.

I think all specials cases have parentheses in the end, so its actually not that bad. Worst case is two pair of parentheses in one line, i.e. resist and absorb.
