grafana's Issues

Dashboard-based navigation between "related" dashboards

This was discussed before and during the summit.

We need a way to provide navigation to related dashboards without having to go to the big Dashboard picker. When we distribute bundles of related dashboards, this becomes very necessary (as it is for Litmus).

This has been requested a few times within the Grafana community.

Possibility of links in top bar? grafana#572

Navigation Panel Type grafana#517

Table of Contents and hierarchy for nav grafana#1378

Linked dashboards: grafana#1617

How should we do this?

Interim plan vs long term? HTML panel with static links?

inline svg breaks when minifying assets

When the html/css/js assets are minified, inline svg's are breaking.

Dashboards incorrectly prompt to Save

Currently whenever you edit the template variables in raintank Dashboards, and then try to navigate away from the Dashboard, you get the "Dashboard has changed" warning modal, even though there has been no changes to the Dashboard.

This likely needs to be a Grafana fix.

more endpoint dashboard tweaks

in rt-endpoint-ping dashboard:
in the ping response range panel:

add consolidateby(max) to max ping latency metric
add consolidateby(min) to min ping latency metric

in all dashboards:
in the status bar panel:

add consolidateby(sum) to all metrics

get release packages working

When the source is built into a release package (go build.go build package) the application is not working.

track internal (gauge) metrics?

i want to track the number of items in the internal alerting dispatch queue (basically len(channel))
what would be the best way to do this? i know we have an internal fork of the go-metrics library but it only seems to support gauges.

show litmus dashboards in dash search/list

litmus dashboards are served by a specialized dashboard controller that loads the dashboards directly from the server. this is pretty much how the DashFromFile controller works except the path to the dashboards is different.

Because these dashboards are not stored in the DB, they do not show up in the dashboards search/list menu.

Initial endpoint dashboard creation

Need initial versions of the following Dashboards created. These will be the "stock" (and non editable) Dashboards that will ship with Litmus.

· Endpoint Summary (attempted)
· Endpoint DNS (attempted)
· Endpoint PING (attempted)
· Endpoint WEB (attempted)
· Collector Summary
· Collector DNS
· Collector PING
· Collector WEB
· Events

Collector List language (configure, edit)

In the elipses menu, you can "edit" a Collector but in the detail view, the tab says "Configuration".

Let's standardize on "configure" and "configuration" as what you do to a Collector, and make no mention to "edit" or "editing"

Litmus "light" theme, and raintank:grafana "dark" alignment

Make sure that the light theme looks snazzy for Litmus
Align the dark theme between raintank and grafana more

"unexpected error" when trying to publish snapshot from litmus dashboard

i'm at https://portal.raintank.io/dashboard/raintank/rt-endpoint-web?var-endpoint=dieter_plaetinck_be&var-collector=All&var-protocol=http

i hit share->snapshot-> publish to snapshot.raintank.io
in network tab i see 4 /render calls, they all succeed
then in console i see

Configure collector styling

When configuring a Collector, the styling in the top nav is not consistent with the rest of the interface (in the Collector dropdown).

automate creation of dashboards

We want users to automatically be provided with our stock dashboards for displaying the litmus data. These dashboards should only be added to organisations when there is data available to be displayed.
eg. When a user adds their first endpoint, the summary status dashboard should be added to their account. When they add their first Ping check, the Ping dashboard should be added.

Cannot rename collector

If you create a collector, save, then try and edit the name, it appears to rename successfully (w/ success message), but switches back to its original name.

Default Menu State: Open

For the raintank build, I'd like to side menu to be open for new users.

Unsure how state is set/saved (if it is), so this might need some quick discussion with @awoods or @torkelo

Managing (becoming) other organizations

The Grafana system admin should (I think) have some way of becoming or switching to any Organization that they want to.

This is necessary for supportability when a system admin is responsible for many Users across many Organizations.

Breadcrumb in top nav not working

Endpoints and Collector links in the top nav should take you to endpoint list and collector list, respectively.

collector enabled/disabled feature does not do anything

Collecters have an 'enabled' field but toggling this does not have any affect on the operation of the collector.

helper Text in New Endpoint

When new Litmus users do not have any Endpoints added, it would be nice to give them some basic instructions on adding an Endpoint.

Here's some sample text that can be displayed if they don't have any Endpoints:

It looks like you don’t have any Endpoints yet.

Add an Endpoint to get started with raintank Litmus. An Endpoint can be anything you want to monitor.

When you add a domain name of your Endpoint, we will automatically detect what we can monitor (eg. PING, HTTP, HTTPS) and suggest a configuration that can be customized.

Add default tags for region for all public collectors

Tags as follows:-

USA
EMEA
ASIAPAC

Change orientation of caret on expand

As a general convention when working with accordion boxes, the orientation of the caret should change when expanded. Here's an example:

`Nullable: false, Default: ""`migration leads to column with null values

       mg.AddMigration("monitor add alerts v1", NewAddColumnMigration("monitor", &Column{
                Name: "health_settings", Type: DB_NVarchar, Length: 2048, Nullable: false, Default: "",
        }))

leads to this. note that the health_settings has NOT NULL set (good), but yet, a new column shows up with a null value?

Collector List language (online, offline)

Keep language consistent.

We refer to collector status as "Online" or "Offline". The header for Collector List should be consistent with this, and changed from "UP|DOWN" to "Online|Offline"

local snapshots don't properly contain the needed the data

on https://portal.raintank.io/dashboard/raintank/rt-endpoint-web?var-endpoint=dieter_plaetinck_be&var-collector=All&var-protocol=http, with timepicker set from 7d ago to now

share->snapshot->local
first time i got this one:
https://portal.raintank.io/dashboard/snapshot/T1LGC84lhjusXNUUHctIOtbo63gI5xG9
note that one out of the four doesn't contain the needed data

then i tried again with firebug open, and got
https://portal.raintank.io/dashboard/snapshot/Cfck10A2wG8TfDDvfqRb1ukdXY9tgMXh
note that all 3 graphs don't work, only the errors panel works.

looking at network tab, i can see the 4 render requests all worked and returned proper json data,
however the first one (for ok/warning/...) returned in about a second, the other three took longer. maybe that's related.

here's what it posted to portal.raintank.io/api/snapshots:

endpoints in endpoint select box only show up when they have data

i added an endpoint B, went to dashboard of pre existing endpoint A and then tried to use the drop down to elect B but if didnt show up, which was confusing

allow going to, say, http check configuration from the http dashboard

when i'm on http dashboard looking at http perf of my blog, i would like an easier way to go to the config of this

Add public facing proxy/web

HTTP->HTTPS
Future scaling / load balancing / etc

wire up Collector tag dashboards

The links to dashboards-by-Collector-tag are dead.

Please wire up multiselect links for the list of Collectors in that tag.

We might use existing endpoint dashboard or create another dashboard for this. Still thinking about it. Important thing is that we can link to dashboard?var-collector= but with the Tag values instead of an individual Collector, and leverage the template multiselect now in Grafana.

New Endpoint Page Adjustments

Checklist for help from AWoods:

Trigger Spinner on "Auto-Discover"
Wire up New Endpoint page to New Endpoint button.
Change options in Frequency Select Box to "Every 10s, Every 30s..."
New resting state & disabled state.
Issue with Enabled button not being checked in both places.
Enabled button collapsing the box.
Collector select button showing results in a select Box.
Wire up Add Endpoint & Cancel buttons.

Tags colors are incorrect on detail pages

When adding tags on the detail pages, they all display with purple backgrounds, this is incorrect.

The colors should all be different based on the hash string.

Summarizing Total Individual Collectors selected and Total Tags selected

Need to get the sum of individual collectors, tag collectors, and grand total available within endpointCollectorSelect.html, line 4. Dont know how to get that out of Angular, unfortunately.

alert scheduling, modulo, modulo offset

Torkel and I decided it makes a lot of sense for initial alerting implementation to just query the monitor table, since the up/down definition is now a rule that is very closely tied to the monitor definition, and will in fact be stored in the monitor table along with the other check parameters. So no need to manage alerting rules in a separate alerting table.
For the alert scheduling, 3 parameters are very important:

frequency should be in sync with data collection. i.e. if a check runs every 10 seconds, so should the alert/health-indicator-updator. this is easy, as there is a frequency column in the monitor table already
when within each period should be the alert trigger? For a given customer all collectors will run at the same time right? And does that go for all checks for a given customer? it looks like it's not the case ( if that's what the monitor.offset column is), let me explain what I mean:
if I have dns check every 60 sec and http check every 10 sec, then i would say my customer id should be hashed and modulo'd by 60, let's say the result is 37, and then that module 10 is 7,
this means the minutely check runs at every minute and 37 seconds, while every 10-second runs at min:07, min:17, min:27,min:37 and so on. the advantage is that even for different frequencies, the point's timing still match up. I think this will become useful later in alerting logic that looks at different series for the same endpoint but where data which is at different resolutions. otherwise scenarios where the minutely check runs at 0:37 and the 10-secondly runs at 0:32 and 0:42 could be very ambiguous and hard to relate. (although admittedly this is not much more than some gut feeling)

anyway my point is in models/monitor.go i saw these 2 fields and i was wondering if modulo == frequency and modulooffset == seconds to wait at the start of each interval?

174   Modulo         int64   `form:"modulo"`
175   ModuloOffset   int64   `form:"modulo_offset"`

i think the best approach would be just hashing customer id to a number, and then storing that number, so you can easily query for the appropriate scheduling offset like so:

select hashed_number % frequency as offset, frequency from monitor

(modulo is supported by both mysql and sqlite)
the advantage is we don't lock ourself into any timeframe.
let's say we later decide to support 10-minutely, then we can always easily retrieve the proper offset that also syncs up with higher-frequency periods.

anyway the alerting logic has to query the offset somehow

we should maintain a special offset variable that tells how long it takes from the collector data to make it into the system and the data to become available for querying, and then some extra time to be safe.
so that we can schedule the alert shortly after the data arriving into the system, but also not too late.
i presume one global variable should be enough to cover all customers and all collectors, where-ever they are? i can imagine later we may implement a service that taps into the stream and keeps tabs on the per-collector delays or continuously queries graphite-api and adjusts this offset automatically.

can't easily find configuration for, say, http check

i have only 1 endpoint and i want to modify the http check config
i have to go to endpoints, select my endpoint and then go to configuration
this is confusing to me because when i think "i want to change my http check config" i really don't think about going to endpoints, especially since I'm a customer who only monitors one site so i don't even think of the concept of endpoints anymore. note that #55 might alleviate this but i wonder if we can perhaps have a side entry "checks" from which i can easily go to my http check config

panel-based navigation

Many dashboards will show summaries of a particular endpoint or collection, it is important that users are able to click a panel to go to another dashboard / set template variables.

For Litmus, we want to be able to navigate to a given Dashboard with a given set of template variables by clicking on a particular panel.

This feature has already been discussed at length by the Grafana community, and some functionality exists within Grafana to help accomplish it:

links to other dashboards grafana#1041

Make Drilldown easier grafana#1575

Whole panel clickable grafana#1377

Drilldown graph link grafana#1232

incorrect display of errors

dns <100% but error bars are all green?
ping 100.00% in orange?
this one should speak for itself:

Event panel parameters

Event panel should be able to accept the $endpoint and $collector variables as arguments (set in Grafana Templates). Should be able to accept single vals (ie. "foo") or Graphite-style globs (ie "{foo,bar,moo}")

Definitely open to accomplishing this some other way but this seemed logical. This will allow it to function with the same filters as the rest of the Dashboards.

Endpoint Summary should categorize unconfigured checks

In endpoint summary, when a check isn't configured we should show that more explicitely and allow the user to configure/enable that protocol. Currently we just show "no data"

Need better control over Input Length, Order and other elements of Endpoint Check Fields

Currently the new & edit endpoint are programmatically getting all the fields from the backend, but I'm not able to see where I have individual control over input lengths and order.

<div class="editor-option rt-input-styles" style="padding-top: 15px; padding-bottom: 5px; width: auto;     height: auto;" ng-repeat="setting in monitor_types_by_name['ping'].settings">
<raintank-setting definition="setting" target="currentSettingByVariable(monitors['ping'], setting.variable)">
</div>

I was going to just try and break out the individual elements and recreate the forms manually, but that seemed silly. Im sure there's a more centralized way to achieve this.

We can also chat about additional features, but this is a good start.

feedback link no longer works

In tinyalpha the feedback link in the bottom is no longer persistent, and when i can catch it it no longer works.

raintank-icons missing

recent changes depend on fonts/raintank-icons.(ttf, eot, woff, svg) but these have not been committed.

users resetting password

(I don't think this is raintank specific but opening here)

There needs to be a way for users to reset their passwords in Grafana.

Currently this is impossible (I think). Only the admin can do this.

tracking important errors

do we have any convention on how we will keep tabs on critical/important error events in grafana?
maybe log to a file and then use heka or logstash to shove them into ES?

datarace in websocket code

once in a while, it's useful to bulid with go build -race and see if anything shows up at runtime.
and something did. a non-threadsafe datastructure is being read from and written to at the same time.

==================

Periodic 'permission denied'

I consistently get periodic 'permission denied' with navigating around the current staging server.

Reloading causes it to go away, but it is definitely an annoyance.

This isn't a one-off issue as it's happening both at home on Windows/Chrome and at work on OSX/Chrome. @mattttt also said this has been happening to him periodically.

map panel

We need to create a map panel to support map functionality around Collectors, both in the Litmus pages as well as the Grafana Dashboards.

Ideally this can be accomplished as a stock Grafana panel, and can be used in an embedded manner in necessary Litmus pages.

Requirements of the map:

Autowindow/autozoom based on the items selected (ie. smart enough to show the world for listing all collectors, but zooming into Europe for EMEA, down to showing New York metro for someone looking at a hypothetical "NYC" tag, etc etc)
Be able to represent 1-5 values on each item in the map (either as a color shade, dots, etc etc), alongside annotations or notes
Make sure its consistent with our look and feel
Ideally not dependent on external accounts / costs

helper Text in Home Dashboard

When new Litmus users log in, it'd be nice to welcome them in the Home dashboard. Eventually this can link to help, chat, docs, etc, etc.

Here's some sample text welcoming a user to Litmus:

Welcome to raintank Litmus!

Litmus allows you to monitor the network quality of anything from anywhere.

Whether you have a simple blog or a globally distributed application, Litmus can help you analyze its performance and availability from around the world.

Litmus is currently in restricted alpha. Your feedback is much appreciated and helps make it better.

Setting template variables via URL parameter doesn't consistently work

Need to be able to set/override Template variables by passing URL params.

Currently trying to pass &var-endpoint=blah&var-collector=bar

Should this work? Am I running into problems with multi variable Templating?

Behavior seems really inconsistent. A lot of times the correct variable will show in the Template drop-down, but the value itself isn't selected. This causes the panels to have no data unless the endpoint is explicitly selected.

Also needs to account for multiple variables too (which can be a graphite style glob eg. "{foo,bar}"..)

endpoint modal tweaks

Some of this will change with Matts new modals, but here are some small tweaks:

Change the text on the button from "New Endpoints" to "New Endpoint"
When adding a new Endpoint, change the description from "Site name" to "Domain name"
When adding a new Endpoint, don't show the "Summary" tab or the button to the Dashboard; neither are valid until the Endpoint is created.

collectors state set to disabled when tags updated

IsGrafanaAdmin

I am little worried that IsGrafanaAdmin is used so much, this is a temporary flag that marks a super admin that will probably replaced with a more detailed role and permission system.

It looks like public collectors are controlled by IsGrafanaAdmin. Is there not a better way to do this? That public collectors bellow to a specific organization and the admin for that org can edit them?

I see conditionals for IsGrafanaAdmin in many places and this feels very dirty and fragile. But I am not sure, just trying to review some raintank grafana code to see if there is anything to worry about long term. This might not be a big issue, just one thing that popped into my head.

The same thing about using isGrafanaAdmin for ApiKeys seems like a big security issue. Basically all remote collectors will have a super duper password that can do everything (or am I missing something?).
