我试图删除prometheus中除了一些列入白名单的指标。我可以选择性地坚持他们：
metric_relabel_configs:
- source_labels: [__name__]
regex: (?i)(metric1|metric2|metric3)
action: keep
但是我想删除所有其他不匹配的指标。有没有直截了当的方法呢？
答案 0 :(得分：5)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_coin_detail);
sectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
viewPager = (ViewPager) findViewById(R.id.graph_container);
setupViewPager(viewPager);
viewPager.setOffscreenPageLimit(10);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
tabLayout.getTabAt(0).setText("1 Day");
tabLayout.getTabAt(1).setText("7 Days");
tabLayout.getTabAt(2).setText("30 Days");
TextView header = findViewById(R.id.newtextViewHead);
coinIMG = (ImageView) findViewById(R.id.imageView2);
button_alert = (CircleButton) findViewById(R.id.button);
button_fav = (CircleButton) findViewById(R.id.button_favorite);
//Calls for intent
Intent intent = getIntent();
//Tabs for fragment
private void setupViewPager(ViewPager viewPager){
SectionsPagerAdapter adapter = new SectionsPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new Fragment_Graph1());
adapter.addFragment(new Fragment_Graph2());
adapter.addFragment(new Fragment_Graph3());
viewPager.setAdapter(adapter);
}
动作会删除所有不匹配的内容，因此单个操作足以执行您想要的操作。
