graphite

问题 I have a scenario as follows. Nginx is being used as a reverse proxy to a apache server listening at port 8080. nginx is running at port 80. There is a wsgi application which is being run by the apache server. Now, I have added a proxy_pass to the nginx configuration such that whatever requests come to localhost/ (nginx port is the default port 80) they get redirected to localhost:8080. Here is an excerpt from the nginx conf file: server { listen 80; proxy_set_header X-Real-IP $remote_addr;

问题 I have Grafana with Graphite metrics. I have a graph showing the EnqueueCount of some specific queue in ActiveMQ. The problem is that the EnqueueCount shows all values since the queue was created, so when I narrow down the time range in Grafana to "today so far", the graph looks like this: I would like it to show only values for current period - I would like the graph to always start at 0. In this case I would like to offset it by -2. There is an offset function, however it is only by

问题 I am currently collecting monitoring metrics with Ganglia and I would like to show graphs with that data with Graphite. I know such an integration is possible, and I found an article describing how it should be done. I am not quite sure exactly how this integration works, especially when I want to send it straight into graphite without parsing the data of the gmetad. Any help on how to integrate Ganglia with Graphite will be great. thanks 回答1: There are two approaches to integrate ganglia

问题 I have a graphite instance that I would like to use memcache server to read from cache. I have done these: Installed memcached on 192.168.101.1 Installed graphite and python-memcached on server 192.168.101.2 I verified that graphite web-app works using opentsdb as backend storage. This is my local_settings.py looks like: SECRET_KEY = 'pass123' TIME_ZONE = 'America/New_York' DEBUG = True MEMCACHE_HOSTS = ['192.168.101.2:11211'] DATABASES = { 'default': { 'NAME': '/opt/graphite/storage/graphite

问题 I am working on AWS RHEL server. Getting this error each time I access the webpage(Webpage showing 500).

问题 I'm installing graphite 0.9.15 on Ubuntu Server 16.04 LTS. During configuration step cd /opt/graphite/webapp/graphite sudo cp local_settings.py.example local_settings.py Then using the command in the official installation instruction: sudo PYTHONPATH=/opt/graphite/webapp/ python manage.py migrate --settings=local_settings Gave information Operations to perform: Apply all migrations: (none) Running migrations: No migrations to apply. Then I went to check the graphite.db sqlite3 graphite.db

问题 There is a function named alias, that I tried as given below http://myhost:80/render?target=alias(my.src.metrics.endTime,"my.target.metrics.success_endTime") But I want to create my.target.metrics.success_endTime persistent in the graphite for my.src.metrics.endTime . so that new values under the my.src... are also available via my.target... . 回答1: However, you can't configure persistent aliases in graphite's UI (webapp), you may create symbolic link on the filesystem, that will behave like

问题 Is it possibile to store time per point with millisecond precision? Since Graphite is based on Whisper I've took a look at whisper.py file. It contains: UnitMultipliers = { 's' : 1, 'm' : 60, 'h' : 60 * 60, 'd' : 60 * 60 * 24, 'y' : 60 * 60 * 24 * 365, } so it seems that it's possibile to record events with a maximum precision of 1s. How can I cope with a system that produces an event every 10ms? 回答1: You can send the data to the carbon-aggregator daemon or Statsd. These are both aggregators,

问题 I am using metrics with dropwizard and I am reporting these to the graphite server. Almost the same way described in the tutorial. https://dropwizard.github.io/metrics/3.1.0/manual/graphite/#manual-graphite But I wanted to configure the graphite properties in the dropwizard yaml file. Something like the following metrics: reporters: - type: graphite host: graphite_server port: 2003 prefix: some_example_metrics How do I then configure this in my dropwizard configuration class in order to use

问题 I have a seriesMetric , and a constantLine (the goal/SLA). I want to be able to "count" the occurances below the line, and divide by the total to get a % within SLA. I know how to do the 2nd part, using asPercent , but I can't figure out how to count the occurrences below the line in Grafana. There's no countif function. I tried currentBelow and averageBelow , but then nothing appeared on my chart (the two lines disappeared). I assume I did something wrong. I think this is a pretty common use
