#mongodb logs for Thursday the 29th of May, 2014
[07:28:02] <user123321> Should I install MongoDB first or PHP-My-ADMIN in Ubuntu? Does any order affect a conflict, could I have some advice? Thanks!
[08:33:43] <nevan> MongoClient::connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known
[08:36:14] <nevan> MongoClient::connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known
[08:37:17] <Gargoyle> nevan: Just because you repeat yourself does not mean you'll get a qucker answer (or any answer at all).
[08:37:53] <Gargoyle> The error means your machine failed to lookup the hostname you are trying to connect to.
[08:38:23] <nevan> sorry but it was an effor to get attention as most of the times before nobody actually responds...sorry again
[08:38:58] <nevan> but when i give single string instead of seeds of replica sets then i do not come across this issue
[08:40:22] <Gargoyle> nevan: People in here give their time freely. If they can answer, they will. If they can't because they don't know or are too busy, then they will keep quiet. Do you really want 346 "I don't know" replies! :-)
[08:45:36] <nevan> @Gargoyle : just replaced the actual IP with (IP) , replica set name with <replicaset> and dbname with <dbname>
[08:49:11] <Gargoyle> OK, I have no knowledge about ZF and MongoDB. However, just by looking at that snippet whatever code is interpreting that line is going to have difficulties with the number of arguments
[08:50:19] <Gargoyle> You could also try single quotes round the mongodb://... connection string to separate it from the array of options
[08:55:50] <nevan> no error whatsoever in logs...restarting instances solves the problem version 2.4.9
[08:58:04] <Gargoyle> rs.status() will tell you current replication status. And there's a free service from mongodb.org called MMS which can give you nice graphs on all sorts of things. :)
[08:58:35] <nevan> i am using that..but its kind of cryptic as which ones are important and critical ?
[11:32:01] <G1eb> hello, strange thing, my documents have fields that are nested docs and the key is a url
[11:32:32] <G1eb> I can lookup the doc using the _id field just fine but if I try that url I get nothing.
[12:17:33] <nevan> i have some field name starting with "$" which is not accecpted by new mongo2.6 ....what can be the most viable solution to this ...any idea
[12:23:30] <ajph> nevan: even in 2.4 You can use any (UTF8) character in the field name which aren't special (contains ".", or starts with "$").
[12:33:34] <radixo> hello guys.. I am trying to follow the http://docs.mongodb.org/manual/tutorial/enable-authentication/ but when I arrive to step "2" (Connect to the MongoDB instance via the localhost exception) I get this error: 2014-05-29T12:27:33.564+0000 Error: couldn't connect to server localhost:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:148
[12:37:31] <nevan> @ajph we have such fields in current db (2.4) but to port it to 2.6 which restricts this
[12:39:58] <ajph> nevan: just because it works doesn't mean you should do it - http://docs.mongodb.org/v2.4/reference/limits/#Restrictions-on-Field-Names
[12:54:28] <tmssgrdn> Hi, I am very new to MongoDB and nosql in general. Is it possible to restrict what goes in a document, or is that not something one would want for MongoDB? More specifically I am thinking of types and "NOT NULL" like restrictions.
[13:50:33] <inad922> How can I set the value of a field in an update call with pymongo if I want to base it on another field in the same object?
[14:21:11] <radixo> ajph: Error while trying to show server startup warnings: not authorized on admin to e xecute command { getLog: "startupWarnings" }
[15:42:39] <dsirijus> a question from a newbie - can i have an Object inside a Document without using another Document via ObjectID?
[15:44:10] <dsirijus> i mean, can a document be {this:String, that:{something:"nothing"}} without 'that' being ObjectID?
[16:00:14] <modcure> when setting the write concern in mongodb to knowledge the write... this knowledgement is only agreeing to the face that the record was commited in memory and not to the data files correct?
[16:00:59] <saml> modcure, http://docs.mongodb.org/manual/core/write-concern/#write-concern-acknowledged
[16:02:43] <Dogevo_> is it reasonable to assume that 'a collection' may contain hundreds of millions of 'small' documents per shard? And allocated memory is a larger determinant to performance than the number of docments per collection??
[16:04:00] <saml> if you are scanning many small documents, it'll be slower than scanning few large documents
[16:04:23] <modcure> saml, it seems the write concern only updates the memory data and not the database but the journal write concern commits the record to disk. is this accurate?
[16:06:23] <saml> if you kill mongod right after getting write response with acknowledged write concern, data will be written to disk. i think
[16:07:12] <modcure> i think it only writes to ram.. if it was written to the data files on disk then whats the point about having a journal file
[16:09:28] <cheeser> there are different levels of write concerns: http://docs.mongodb.org/manual/core/write-concern/
[16:10:49] <dsirijus> a premature optimization question - i have a certain object in user document, over which i'll probably need to iterate very frequently (a second or few)...
[16:12:13] <saml> http://techidiocy.com/types-write-concern-mongodb-performance-vs-persistence/ modcure
[16:14:35] <dsirijus> well, i'm new to databases in general, so i might reformulate question to something i know i want
[16:16:00] <dsirijus> it's irrelevant for users not currently logged in (though it needs to be correct value when he gets back in)
[16:16:46] <dsirijus> but, online users request that value very frequently in session (say, every half a minute or so, the frontend can simulate it growing in-between the "syncs")
[16:19:03] <Dogevo_> that's less a mongodb concern and more a point about your own data design I assume
[16:30:58] <Dogevo_> What's a recommended strategy people have for dealing with documents that could frequently extend beyond the document size limit?
[16:31:15] <dsirijus> ok, there's this energy, in theory on high level players that value updates almost every second....
[16:31:40] <dsirijus> so, in frontend, we've just defined "sync points" where user either wants to display that value, or spend some of it and update it
[16:32:14] <dsirijus> database stores time of the last "sync point" request, and node just calculates the new value (validates if he's spending energy)...
[16:35:33] <dsirijus> the visual cue of that value updating at perfect rate (every frame of the game) on frontend is just frontend ticking, hoping someone doesn't play with system clock or memory hacking
[17:17:57] <synth_> hello, i was curious if there's a way to silence this warning? import pymongo produces: /usr/local/lib/python2.7/dist-packages/pymongo-2.6_-py2.7-linux-x86_64.egg/pymongo/thread_util.py:31: UserWarning: libevent version mismatch: system version is '2.0.19-stable' but this gevent is compiled against '2.0.16-stable'
[18:00:02] <dsirijus> can mongo do funky stuff like have a key identifier (in key-value pair) be value from some other collection from some other key?
[18:02:42] <dsirijus> say a have a document {_id:ObjectID<1>, key:"value"}. can i create, dynamically, another document that's {_id:ObjectID<2>, value(string from that first document):"whatever"}?
[18:15:08] <synth_> saml, now getting this: http://sprunge.us/UFaG?sh same error but now includes from gevent.lock import BoundedSemaphore as GeventBoundedSemaphore
[18:19:46] <jhuel> and i can't find a way to not get a compilation error of LNK1104: cannot open file 'mongoclient-gd.obj'
[19:06:13] <revoohc> anyone now why the journal on one secondary node would be significantly than the journal on master or the other secondary node in a replicaset?
[19:11:25] <Siddharth123> I'm looking for some help with regards to designing my app that uses MongoDB at the back-end.
[19:12:26] <Siddharth123> The questions are particularly design related, I guess. And I'm looking for the best way to store the data in question.

[19:25:41] <bschrock> Hello, I am trying to remove a config server from a sharded replset (that is not actually partitioned) and I get this error: { "ok" : 0, "errmsg" : "Can't remove last shard" }. Does anyone know why?
[19:54:12] <ranman> I could be mistaken but I don't think that's a scatter gather query I think it will only hit the shards it needs to
[20:00:59] <jtreminio> Hi all. I have been experiencing very slow download speeds for mongo through official repos. Is this a known issue?
[21:22:37] <bdha> Hey folks... I'm trying to enable the httpinterface. I've set httpinterface=true in mongod.conf and restarted. auth=false. When I hit :28017, however, I get prompted for a user/pass.
[23:07:46] <astropirate> When I manually run mongod using "sudo mongod" I am able to access my DB from another server on the same network. However, when I run it using a service using "sudo service mongod start" I am not able to. It shows it running when I check its status as well and can use the mongo client with it
[23:08:17] <astropirate> i installed it by following this guide: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
[23:13:11] <astropirate> it apears that the mongod service only listens on 127.0.0.1 and not any other address
[23:24:15] <daidoji> hello, for those using pymongo, is there any way to recover all of the operations from the BulkOperationBuilder on exception?
[23:24:59] <daidoji> can I print out all the insert ops in order to review in the logs which records had trouble?
